AbstractWe demonstrate experimentally that Tamm plasmons in the near infrared can be supported by a dielectric mirror interfaced with a metasurface, a discontinuous thin metal film periodically patterned on the sub-wavelength scale. More crucially, not only do Tamm plasmons survive the nanopatterning of the metal film but they also become sensitive to external perturbations as a result. In particular, by depositing a nematic liquid crystal on the outer side of the metasurface, we were able to red shift the spectral position of Tamm plasmon by 35 nm, while electrical switching of the liquid crystal enabled us to tune the wavelength of this notoriously inert excitation within a 10-nm range.

The total internal reflection ellipsometry method was used to analyse the angular spectra of the hybrid Tamm and surface plasmon modes and to compare their results with those obtained using the conventional single SPR method. As such type of measurement is quite common in commercial SPR devices, more detailed attention was paid to the analysis of the p-polarization reflection intensity dependence. The conducted study showed that the presence of strong coupling in the hybrid plasmonic modes increases the sensitivity of the plasmonic-based sensors due to the reduced losses in the metal layer. The experimental results and analysis of the optical responses of three different plasmonic-based samples indicated that the optimized Tamm plasmons ΔRp(TP) and optimized surface plasmons ΔRp(SP) samples produce a response that is about five and six times greater than the conventional surface plasmon resonance ΔRp(SPR) in angular spectra. The sensitivity of the refractive index unit of the spectroscopic measurements for the optimized Tamm plasmon samples was 1.5 times higher than for conventional SPR, while for wavelength scanning, the SPR overcame the optimized TP by 1.5 times.

Two schemes of excitation of a Tamm plasmon polariton localized at the interface between a photonic crystal and a nanocomposite with near-zero effective permittivity have been investigated in the framework of the temporal coupled-mode theory. The parameters of the structure have been determined, which correspond to the critical coupling of the incident field with a Tamm plasmon polariton and, consequently, ensure the total absorption of the incident radiation by the structure. It has been established that the spectral width of the absorption line depends on the scheme of Tamm plasmon polariton excitation and the parameters of a nanocomposite film. The features of field localization at the Tamm plasmon polariton frequency for different excitation schemes have been examined. It has been demonstrated that such media can be used as narrowband absorbers based on Tamm plasmon polaritons localized at the interface between a photonic crystal and a nanocomposite with near-zero effective permittivity.

Low-cost 1D plasmonic photonic structures supporting Tamm plasmon polaritons and cavity modes were employed for optical signal enhancement, modifying the commercially available quartz crystal microbalance with dissipation (QCM-D) sensor chip in a combinatorial spectroscopic ellipsometry and quartz microbalance method. The Tamm plasmon optical state and cavity mode (CM) for the modified mQCM-D sample obtained sensitivity of ellipsometric parameters to RIU of ΨTPP = 126.78 RIU−1 and ΔTPP = 325 RIU−1, and ΨCM = 264 RIU−1 and ΔCM = 645 RIU−1, respectively. This study shows that Tamm plasmon and cavity modes exhibit about 23 and 49 times better performance of ellipsometric parameters, respectively, for refractive index sensing than standard spectroscopic ellipsometry on a QCM-D sensor chip. It should be noted that for the optical biosensing signal readout, the sensitivity of Tamm plasmon polaritons and cavity modes are comparable with and higher than the standard QCM-D sensor chip. The different origin of Tamm plasmon polaritons (TPP) and cavity mode (CM) provides further advances and can determine whether the surface (TPP) or bulk process (CM) is dominating. The dispersion relation feature of TPP, namely the direct excitation without an additional coupler, allows the possibility to enhance the optical signal on the sensing surface. To the best of our knowledge, this is the first study and application of the TPP and CM in the combinatorial SE-QCM-D method for the enhanced readout of ellipsometric parameters.

Chiral-selective Tamm plasmon polariton (TPP) has been investigated at the interface between a cholesteric liquid crystal and a metasurface. Different from conventional TPP that occurs with distributed Bragg reflectors and metals, the chiral–achiral TPP is successfully demonstrated. The design of the metasurface as a reflective half-wave plate provides phase and polarization matching. Accordingly, a strong localized electric field and sharp resonance are observed and proven to be widely tunable.

Ce travail de thèse porte sur l'étude expérimentale de structures à plasmons Tamm actives, composées d'une couche d'argent déposée sur un miroir de Bragg semiconduc teur AlGaAs/GaAs contenant des puits quantiques InGaAs. Après une description des modes Tamm et de leurs propriétés planaires, nous nous sommes intéressés plus parti culièrement aux structures à plasmons Tamm confinés par un micro-disque de métal. Des mesures de photoluminescence ont permis de mettre en évidence un effet laser dans ces structures. Une étude approfondie a montré une évolution du seuil laser en fonction du diamètre du disque, résultant d'un compromis entre confinement et pertes. Dans un second temps, nous avons étudié la réponse optique de structures à plasmon Tamm asy métriques, où le plasmon Tamm est confiné par des micro-rectangles. Cette asymétrie lève la dégénérescence en énergie qui existe entre les deux modes linéairement polarisés de la structure. Ceci, associé à un fort désaccord spectral entre l'émission des puits et le plasmon Tamm, permet d'obtenir une émission laser linéairement polarisée . Enfin, nous présentons l'étude d'une structure à plasmon Tamm comportant un réseau permettant le couplage du plasmon Tamm au plasmon de surface de l'interface air/argent. Grâce à des mesures tirant parti de l'aspect propagatif des modes, nous avons mis en évidence un battement entre plasmon Tamm et plasmon de surface
This thesis focuses on the experimental study of actives Tamm plasmons structures, consisting in a layer of silver deposited on a AlGaAs/GaAs semiconductor Bragg mir ror which con.tains InGaAs quantum wells. After describing Tamm planar modes and their properties, we focused particularly on structures where Tamm plasmons are la terally confined by a metallic micro-disk. Photoluminescence measurements have been carried out in order to demonstrate lasing in these structures. A comprehensive study has shown a change in the lasing threshold with the diameter of the disk, resulting from a compromise between the confinement and the lasses. Secondly, we studied the optical response of asymmetric Tamm plasmon structures, where the Tamm plasmon is confined by micro-rectangles. This asymmetry lifts the degeneracy of energy between the two linearly polarized modes of the structure. Combined with a strong spectral de tuning between the quantum wells emission and the Tamm plasmon, this allows linearly polarized laser emission to set-up. Finally, we present the study of a Tamm plasmon structure comprising a gratting to couple the Tamm plasmon to the surface plasmon at the silver/air interface. Thanks to propagation measurements, we have highlighted the beating between Tamm plasmon and surface plasmon modes

Les capteurs d'indice de réfraction sont très largement employés dans l'industrie et la santé. Ils trouvent des applications aussi bien en contrôle de qualité que pour la détection d'espèces en chimie et biochimie. Si l'utilisation de plasmons de surface pour ces applications est très répandue, ceux-ci souffrent néanmoins de défauts, parmi lesquels de faibles facteurs de qualité. Plusieurs solutions existent pour résoudre ce problème, tels que le couplage avec d'autres modes de résonance ou l'utilisation d'effets magnéto-optiques.Dans ce travail, nous nous intéressons aux modes de Tamm optiques, aussi appelés plasmons de Tamm, et à leurs avantages pour la réalisation de capteurs d'indice de réfraction. Nous étudions dans un premier temps numériquement les modes de Tamm pouvant êtres excités en utilisant une surface structurée, composée d'un réseau de nanorubans, ainsi que l'influence sur la sensibilité de l'utilisation d'un tel réseau.Nous confrontons ensuite ces résultats numériques à l'expérience en fabriquant et en caractérisant un capteur d'indice de réfraction basé sur ce principe.Nous explorons pour finir l'utilisation d'effets magnéto-optiques (TMOKE) pour améliorer ce capteur, de façon analogue aux travaux menés dans le cadre des capteurs plasmoniques
Refractive index sensors are widely used in industry and health sectors. They find applications in quality control as well as for species detection in chemistry and biochemistry. Although the use of surface plasmons for these applications is widespread, they nevertheless suffer from shortcomings, including low quality factors. Several solutions exist to solve this problem, such as coupling with other resonance modes or using magneto-optical effects.In this work, we focus on optical Tamm modes, also called Tamm plasmons, and their advantages for the realization of refractive index sensors. We first study numerically the Tamm modes that can be excited on a structured surface, using a nanoribbon grating, as well as the influence on the sensitivity of such a grating.We then confront these numerical results with experience by fabricating and characterizing a refractive index sensor based on this principle.We finally explore the use of magneto-optical effects (TMOKE) to improve this sensor, in a way similar to the work carried out in the context of plasmonic sensors

The subject of this thesis is the investigation of organic microcavities with implemented unstructured and laterally structured metal layers. The optical properties are studied by means of various spectroscopic techniques and are compared to conventional metal-free devices. It is shown that the large expected absorption caused by the embedded metal is reduced compared to the case of a free-standing metal layer of the same thickness. As a consequence of the interaction of the photonic cavity mode with the metallic structures, two new coupled modes emerge which are called Tamm plasmons. The strength of this coupling and the resulting spectral difference of these modes are defined by the thickness of both the metal layer and the adjacent dielectric layers. These control parameters enable the optimization of the structural design. Accordingly, coherent emission from Tamm plasmons is realized at room temperature. An analytical approach is developed accounting for the experimentally observed polarization splitting of detuned resonances. Next, laterally structured metal layers embedded into organic microcavities are considered. The structuring leads to a confinement of the photonic density of states evident from a clear discretization in energy of the corresponding modes. Applying a photolithographic technique to structure the metal layer into a pattern of regularly placed stripes leads to additional effects due to the resulting periodicity. By exciting this hybrid structure above a certain threshold, periodic arrays of localized cavity modes and metal-based Tamm plasmons are generated. These Bloch-like excited states are capable of phase coupling across the grating. Additionally, surface plasmon polaritons (SPPs) are excited propagating at the interface of the silver and the adjacent dielectric layers. Thanks to the periodicity of the metallic stripes, SPPs are subject to efficient Bragg scattering into the light cone in air. Modes up to order number 30 are detectable as quasi-linear periodic lines in the dispersion pattern. A Fourier analysis reveals an in- or out-of-phase coupling of the modes and a spread of the coherence over macroscopic distances of more than 40 µm. This strategy of embedding metal patterns into an organic microcavity yields a viable route towards electrically contacted organic solid-state lasers
In dieser Arbeit werden erstmals dünne, unstrukturierte sowie lateral strukturierte metallische Schichten in organische Mikroresonatoren eingebettet und anschließend die optischen Eigenschaften mittels spektroskopischer Verfahren untersucht. Es zeigt sich, dass die erwarteten hohen optischen Verluste durch die Absorption des elektrischen Feldes im Metall deutlich reduziert sind, verglichen mit dem Fall einer freistehenden, nicht eingebetteten Metallschicht gleicher Dicke. Als Folge der Wechselwirkung der photonischen Kavitätsmode mit dem Metall spaltet diese in zwei miteinander gekoppelte Moden auf. Diese neuartigen Moden werden als Tamm-Plasmonen bezeichnet. Die Kopplung sowie die spektrale Differenz beider Moden ist zum einen durch die optischen Eigenschaften und die Dicke der eingebetteten Metallschicht definiert, zum anderen durch die optische Dicke der angrenzenden dielektrischen Schichten. Dadurch ist eine Optimierung des Systems im Hinblick auf Absorption und Emissionswellenlänge der Bauteile möglich, so dass selbst bei Raumtemperatur kohärente Emission eines Tamm-Zustands erzielt werden kann. Eine erarbeitete analytische Rechnung bestätigt und erklärt die experimentell gemessene, polarisationsabhängige Aufspaltung der auftretenden resonanten Moden. Im zweiten Teil der Arbeit sind organische Mikroresonatoren, deren eingebettete Metallschicht in lateraler Richtung auf verschiedene Weisen strukturiert sind, Gegenstand der Untersuchungen. Als Folge dieser Strukturierung kommt es zur lateralen Beschränkung der photonischen Zustandsdichte, was durch eine Diskretisierung der Energiespektren der resultierenden optischen Moden experimentell nachweisbar ist. Werden periodische Metallstreifen mittels Photolithographie erzeugt, so kommt es neben einer weiteren Beeinflussung der Zustandsdichte auch zu Effekten, die durch diese Periodizität bedingt sind. Entsprechend reproduziert sich die Kavitätsmode mehrfach im Impulsraum. Oberflächenplasmonen, die auf der Grenzfläche zwischen dem Metall und den dielektrischen Schichten propagieren, werden auf Grund der Periodizität bis in den experimentell zugänglichen Lichtkegel gestreut. Dabei werden Plasmonenresonanzen bis hin zur 30. Ordnung gemessen. Im letzten Experiment werden derart periodisch strukturierte Metall-Organik-Mikroresonatoren auf ihre Lasertätigkeit hin untersucht. Eine lokal begrenzte optische Anregung mittels eines gepulsten Lasers führt zur Ausbildung verschiedener Bloch-ähnlicher Moden, deren Kohärenz sich lateral bis zu 40 µm ausbreitet. Eine Fourieranalyse zeigt eindeutige und feste Phasenbeziehungen zwischen angrenzenden Maxima der Moden. Zusammenfassend ergeben sich interessante metall-organische Systeme, die minimale Absorption und niedrige Laserschwellen aufweisen und die prinzipielle Eignung zur elektrischen Kontaktierung besitzen

Les plasmons Tamm, ou modes Tamm optiques, sont des modes électromagnétiques présents à l'interface entre un miroir de Bragg (DBR) et une couche métallique. Ces modes présentent un fort intérêt pour la réalisation de nouvelles sources de lumière, notamment grâce à la partie métallique, qui peut d'une part fournir un contrôle et un confinement micrométrique à trois dimensions du mode optique, et d'autre part assurer l'injection d'un courant électrique dans la structure pour y exciter un milieu émetteur. De nombreuses sources de lumière pourraient être réalisées grâce à cette double fonction du métal, comme des sources polarisées intégrées, des générateurs de plasmons de surface ou encore des tableaux de laser adressables à grande échelle. Mon travail de doctorat a consisté à pousser les sources de lumière Tamm vers l'applicatif, en développant leur fonctionnement à température ambiante et en excitation électrique, par opposition aux démonstrations à température cryogénique et en pompage optique effectuées jusqu'alors. Ce développement a été effectué sur des structures semi-conductrices basées sur des alliages ternaires d'AlGaAs, mais est hautement transposable à d'autres familles de matériaux. La première partie de ce travail s'est concentrée sur l'obtention d'un effet laser à température ambiante. Grâce à une amélioration de la structure, consistant à insérer une couche de bas indice entre le DBR semi-conducteur et le métal, les pertes ohmiques dans ce dernier ont été réduites, ce qui a permis d'atteindre le régime laser à température ambiante. Le second volet de cette thèse concerne l'injection électrique des sources de lumière à mode Tamm. Partant d'un DBR dopé, deux procédés de micro-structuration en salle blanche ont été élaborés pour permettre cette injection. Le premier, inspiré de techniques usuelles de micro-fabrication, n'a pas fait ses preuves, en raison de la dégradation de la surface du DBR par certaines étapes classiques de structuration, et de la forte sensibilité du plasmon Tamm à la composition de surface du DBR. Nous avons donc développé une méthode de structuration alternative. Son originalité repose dans la protection permanente de la surface du DBR destinée au contact avec le métal. Cette nouvelle méthode a permis la fabrication des premières diodes électroluminescentes basées sur l'émission dans un mode Tamm. Leur caractérisation a montré la réussite de l'excitation du plasmon Tamm par l'injection électrique des émetteurs à puits quantiques, et prouve la possibilité d'utiliser un unique élément métallique pour confiner le mode optique et injecter les porteurs de charge. Ces résultats constituent une étape importante vers le développement d'une variété de sources de lumière intégrées utilisant les modes Tamm
Tamm plasmons, or optical Tamm states, are electromagnetic modes that exist at the interface between a Distributed Bragg Reflector (DBR) and a metallic layer. They are of high interest for the design of new light sources, thanks to the metallic part, which can provide 3D confinement and control of the optical mode but also electrical injection of the structure, in order to excite light emitters. Many light emitting devices could be realised using this dual function, such as integrated polarised light sources, surface plasmon generators or large-scale addressable laser arrays. This PhD work mainly consisted in pushing Tamm light emitting devices towards applicability, with the development of their room-temperature operation and electrical pumping, as opposed to previous demonstrations which were carried out under cryogenic temperature and optical pumping. Semiconducting heterostructures based on ternary alloys of AlGaAs were used for this development, but our results are highly transposable to other families of materials. The first part of this work focused on obtaining a laser effect at room temperature. By improving the structure with the insertion of a low-index layer between the semiconductor DBR and the metal, the ohmic losses in the metal were reduced, thus enabling lasing operation at room temperature. The second part of this work was about achieving the electrical injection of Tamm-based light sources. Starting from a doped DBR with quantum wells, we developed two processes, mostly based on cleanroom microfabrication techniques, to enable electrical injection. The first one, inspired by common microfabrication techniques, has not proved to be successful, due to the degradation of the DBR surface by some standard fabrication steps, and to the strong sensitivity of the Tamm plasmon to the surface composition of the DBR. Therefore, we developed a second method. Its originality lies in a permanent protection of the part of the DBR on which the metallic element will be deposited to form the Tamm mode and inject electrical current. This new method allowed the fabrication of the first light-emitting diodes based on Tamm mode emission. With electro-optical measurements, we demonstrated the excitation of the Tamm plasmon state through electrical pumping of the quantum wells, and proved the possibility to use a single metallic element to confine the optical mode and bring charge carriers into the structure. These results are an important step towards the development of new integrated light emitting devices using Tamm modes

We discuss approaches to increase the light outcoupling efficiency in organic microcavity (MC) lasers and organic light-emitting diodes (OLEDs). We find that the introduction of metals into the cavities leads to additional Tamm-plasmon polariton modes, while the corrugation of metal contacts, such as perforated m-size holes or a periodic array of metal stripes, leads to 2D confinement of the cavity modes, which in turn reduces the lasing threshold in MCs. Furthermore, we elucidate light loss mechanisms in OLEDs and reveal how external dielectric layers and periodic gratings can be used to enhance outcoupling from the OLED cavity.

Exziton-Polaritonen in Mikrokavitäten sind Quasi-Teilchen, die unter bestimmten physikalischen Konditionen kondensieren und damit in einen energetisch gleichen, gemeinsamen makroskopischen Quantenzustand (MQZ) übergehen können. Exziton-Polariton-Kondensate können mithilfe von akustischen Oberflächenwellen moduliert werden, um ihre Eigenschaften zu verändern. Dies ist insbesondere von großer Relevanz für zukünftige Anwendungen. In dieser Arbeit wurden die Struktur sowie die Dynamik der Exziton-Polariton-Kondensate in den durch die akustischen Oberflächenwellen erzeugten quadratischen Gittern untersucht. Es wurde dazu die Wellenfunktion der Exziton-Polariton-Kondensate im Rahmen der spektroskopischen und zeitaufgelösten Messungen im Orts- und Impulsraum abgebildet. Die MQZ wurden in einer optisch-parametrischen Oszillatorkonfiguration resonant angeregt. Die spektroskopischen Messungen zeigten, dass Exziton-Polariton-Kondensate in akustischen quadratischen Gittern aus unterschiedlichen MQZ, nämlich aus einem zwei-dimensionalen Gap-Soliton (2D GS) umgeben von mehreren ein-dimensionalen MQZ, und einem inkohärenten Strahlungshintergrund zusammengesetzt sind. Im Rahmen der zeitaufgelösten Experimente wurde die Dynamik der Wellenfunktion des 2D GS untersucht. Die zeitaufgelösten Ergebnisse zeigten, dass sowohl die Intensität der von dem 2D GS emittierten Photolumineszenz (PL) als auch die Kohärenzlänge des 2D GS zeitlich oszillieren. Die Intensität der PL und die Kohärenzlänge hängen von der Anregungsleistung, der Größe des Laserspots sowie von der relativen Position des akustischen Gitters und dem Laserspot ab. Im Ausblick dieser Arbeit wurde theoretisch die Anregung von Tamm-Plasmon/Exziton- Polaritonen (TPEP) sowie deren Modulation mithilfe von akustischen Oberflächenwellen diskutiert. TPEP entstehen durch die Superposition der in der Grenzschicht zwischen Mikrokavität und Metall angeregten Tamm-Plasmonen und den in der Mikrokavität erzeugten Exziton-Polaritonen.
Microcavity (MC) exciton-polaritons can form condensates, i.e. macroscopic quantum states (MQSs), as well under a periodic potential modulation. The modulation by a surface acoustic wave (SAW) provides a powerful tool for the formation of tunable lattices of MQSs in semiconductor MC. In this work, fundamental aspects of the structure and dynamics of exciton-polariton condensate in acoustic square lattices were investigated by probing its wavefunction in real- and momentum space using spectral- and time-resolved studies. The MQSs were resonantly excited in an optical parametric oscillator configuration. The tomographic study revealed that the exciton-polariton condensate structure self-organises in a concentric structure, which consists of a single, two-dimensional gap soliton (2D GS) surrounded by one-dimensional MQSs and an incoherent background. 2D GS size tends to saturate with increasing particle density. The experimental results are supported by a theoretical model based on the variational solution of the Gross-Pitaevskii equation. Time-resolved studies showed the evolution of the 2D GS wavefunction at the acoustic velocity. Interestingly, the photoluminescence (PL) intensity emitted by the 2D GS as well as its coherence length oscillate with time. The PL oscillation amplitude depends on the intensity and the size of the exciting laser spot, and increases considerably for excitation intensities close to the optical threshold power for the formation of the MQS. In the outlook, the formation of Tamm-Plasmon/Exciton-Polariton (TPEP) hybrid states and their modulation by SAWs was theoretically discussed. Here, the upper DBR is partly replaced by a thin metal layer placed on top of the MC. In this case, TPEP form by the superposition of Tamm plasmons at the metal-semiconductor interface and the exciton-polaritons in the MC.

Organic microcavities comprising the host:guest emitter system Alq3:DCM offer an interesting playground to experimentally study the dispersion characteristics of laterally patterned microlasers due to the broad emission spectrum and large oscillator strength of the organic dye. By structuring of metallic or dielectric sublayers directly on top of the bottom mirror, we precisely manipulate the mode structure and in fluence the coherent emission properties of the device. Embedding silver layers into a microcavity leads to an interaction of the optical cavity-state in the organic layer and the neighboring metal which red-shifts the cavity resonance, creating a Tamm-plasmon-polariton state. A patterning of the metal can in turn be exploited to fabricate deep photonic wells of micron-size, efficiently confining light in lateral direction. In periodic arrays of silver wires, we create a Kronig-Penney-like optical potential in the cavity and in turn observe optical Bloch states spanning over several photonic wires. We modify the Kronig-Penney theory to analytically describe the full far-field emission dispersion of our cavities and show the emergence of either zero- , π-, or 2π- phase-locking in the system. By investigating periodic SiO2 patterns, we experimentally observe stimulated emission from the ground and different excited discrete states at room temperature and are able to directly control the laser emission from both extended and confined modes of the photonic wires at room-temperature.

Abstract A continuous wave with a cubic nonlinearity in an anomalous dispersion regime is known to develop instability with respect to small modulations in amplitude or in phase, called modulational instability. The phenomenon of modulational instability was discovered in fluids (Ostrovskii 1963, 1966; Whitham 1965; Benjamin and Feir 1967), in nonlinear optics (Bespalov and Talanov 1966; Karpman 1967), and in plasmas (Taniuti and Washimi 1968; Tam 1969; Hasegawa 1970, 1971). Modulational instability of a light wave in a fibre was suggested by Hasegawa and Brinkman (1980) as a means to generate a far infrared light source. Akhmediev et al. (1986, 1987) studied the modulational instability by constructing exact periodic solutions of the NLS equation. The first experimental verification of the modulational instability of a light wave in a fibre was made by Tai et al. (1986a). The modulational instability can also be induced by a mixture of a small amplitude light waves with the frequency separation (with respect to the carrier cw wave) falling into the sideband frequency range of instability (Hasegawa 1984). This induced modulational instability can be used to generate an ultra short pulse train with a desired repetition rate. The first experimental evidence of an induced modulational instability was also produced by Tai et al. (1986b). Modulational instability can also be produced by cross phase modulation (Berkhoer and Zakharov 1970; Agrawal 1987). This chapter is devoted to presenting theoretical and experimental analyses of modulational instabilities in fibres.

Phase-change materials (PCMs) provide a specific combination of properties. The binary semiconducting chalcogenide Sb2S3 is consider one of the promising candidates, especially its intrinsic high refractive index, low loss and wide bandgap properties, in near infrared (NIR). Here, the Sb2S3 transformation from amorphous to crystal state embedded between the distribute Bragg reflector (DBR) and metal layer. At the interface between DBR and metal layer in specific parameter, Phase-change Tamm plasmon–polariton (PC-TPP) resonance could be produce. The PC-TPP resonance has a 70 nm modulation wavelength. Also, the resonance achieves around 100 nm-shifted in NIR at the proper incident angle.

Annotation:

Tamm plasmon polariton (TPP) is proposed to demonstrate the ultra-sharp resonance and strong fields confinement. Different applications from UV to NIR are presented, including selective thermal emissions, UV lasers, chirality mirrors, sensors, etc. A DBR-side TPP structure can overcome the limitations of the intrinsic property of the metal, which can support a stronger and narrower TPP resonance. The lithography-free, low cost, and refractory feature of the DBR-side TPP structures pave more possibilities for applications in nanophotonics.

Tamm-plasmon polaritons form between the distributed Bragg mirrors and the metal. It can be directly excited from external light sources and induced by both transverse magnetic/electric modes. We propose a wavelength-sized cavity of a 1-dimensional lattice of silver strips with Si/SiO2 DBRs, which behaves like a photonic crystal nanobeam cavity.
