Abstract:
Exciton–polariton lasers under fermions injection: a condensation of exciton–polaritons was achieved in a microcavity sandwiched by two gradually doped distributed Bragg reflectors with electrical pumping. The polariton laser with an electron–polariton scattering process offers a platform to investigate the interaction between bosons and fermions and an effective way to generate coherent light.

Abstract:
Under adequate conditions, cavity polaritons form a macroscopic coherent quantum state, known as polariton condensate. Compared to Wannier-Mott excitons in inorganic semiconductors, the localized Frenkel excitons in organic emitter materials show weaker interaction with each other but stronger coupling to light, which recently enabled the first realization of a polariton condensate at room temperature. However, this required ultrafast optical pumping, which limits the applications of organic polariton condensates. We demonstrate room temperature polariton condensates of cavity polaritons in simple laminated microcavities filled with biologically produced enhanced green fluorescent protein (eGFP). The unique molecular structure of eGFP prevents exciton annihilation even at high excitation densities, thus facilitating polariton condensation under conventional nanosecond pumping. Condensation is clearly evidenced by a distinct threshold, an interaction-induced blueshift of the condensate, long-range coherence, and the presence of a second threshold at higher excitation density that is associated with the onset of photon lasing.

Abstract:
We report a device that provides coherent emission of phonon polaritons, a mixed state between photons and optical phonons in an ionic crystal. An electrically pumped GaInAs/AlInAs quantum cascade structure provides intersubband gain into the polariton mode at λ = 26.3 μm, allowing self-oscillations close to the longitudinal optical phonon energy of AlAs. Because of the large computed phonon fraction of the polariton of 65%, the emission appears directly on a Raman spectrum measurement, exhibiting a Stokes and anti-Stokes component with the expected shift of 48 meV.

Abstract:
The spectra of exciton-polariton photoluminescence from cylindrical microcavities under optical excitation below and above the threshold of transition to the polariton laser regime under conditions of strong exciton-photon coupling were studied. At relatively weak optical excitation, lateral quantization modes of polaritons and whispering gallery modes appeared. Both the spectral distribution of these modes and the spatial dependence of their wave functions in the resonator plane were observed. With an increase in the excitation intensity and a transition to the polariton laser regime, only one, the longest-wavelength lasing line remained in the spectrum. It has been suggested that under strong optical excitation, the spectrum contains not only exciton-polariton radiation, but also trion-polariton radiation.

Abstract:
Les polaritons de cavité sont des quasi-particules, partiellement matière-t partiellement lumière, crées lors du couplage fort d'un exciton et d'un photon de cavité. A une certaine température et densité de particules, les polaritons de cavité peuvent subir une transition de phase de type quasi-Bose-Einstein et condenser dans l'état de plus basse énergie du système; dans ces conditions, la cavité émet de la lumière cohérente et le dispositif associé est appelé laser à polaritons. ZnO est l'un des matériaux les plus adaptés pour la fabrication des lasers à polaritons fonctionnant à température ambiante, en raison de ses excellentes propriétés excitoniques. Cependant, des difficultés techniques ont empêché la réalisation de microcavités à base de ZnO pendant longtemps. Dans cette thèse nous présentons la fabrication de microcavités à base de ZnO par deux approches différentes, ce qui a permis de surmonter les difficultés technologiques existantes et ont permis d'obtenir des figures de mérite avec des valeurs records (pour le facteur de qualité ainsi que pour l'éclatement de de Rabi). Des lasers à polaritons fonctionnant à température ambiante ont été démontré dans les deux cas. Dans la microcavité entièrement hybride, des condensats de polaritons ont été étudiés dans une gamme de désaccord exciton-photon sans précédents, et de basse température à température ambiante; ceci a permis d'obtenir, pour la première fois, un diagramme de phases complet. Cette thèse ouvre la voie à une polaritonique appliquée fonctionnant à température ambiante.

Abstract:
Polaritons are lightweight bosonic quasiparticles that result from the strong coupling of light with an exciton transition inside a microcavity. A sufficiently dense cloud of polaritons condenses into a polariton condensate, a state of matter showing macroscopic coherence and superfluid properties, whose dynamics are influenced by the cycle of constant pumping and decay of polaritons. This thesis begins with an introduction on the particle and wave properties of the polariton condensate, followed by a theoretical description of two-dimensional Bose-Einstein condensation (BEC) and a section on simulation of polariton condensates. The optical setup and the microcavity sample are presented thereafter, including holographic laser shaping with a spatial light modulator (SLM), which allows exciting the microcavity with arbitrarily shaped pump geometries. Experimental results comprise optical control of polariton condensates, and dipolaritons. First, optical blueshift trapping and energy synchronisation (phase locking) of condensates are introduced. The transition from phase-locked condensates to an optically trapped condensate is investigated for a configuration of N pump spots arranged on a circle of varying diameter. Differences between these two condensate types are highlighted in the discussion section. Next, two parallel pump laser lines with small separation are investigated, which create a one-dimensional waveguide with strong uniform gain. Optically guided polaritons are investigated in this configuration with respect to coherence, flow speed, temperature and chemical potential. Observations hint that coherence arises below the condensation threshold simply from the chosen geometry of the system. The final chapter is dedicated to dipolaritons (polaritons with a static dipole moment) which form when polaritons strongly couple to indirect excitons in coupled quantum wells. In this system quantum tunnelling of electrons can be controlled with bias voltage. This allows tuning the dipolariton properties optically and electrically, with exciting prospects for future experiments. A conclusion and outlook section rounds off this work.

(iii) Enfin, le développement d'une technique d'excitation à deux photons pour les polaritons dans les microcavité semiconductrices est décrit dans la dernière partie du travail de thèse. La première partie du manuscrit étudie les propriétés d'émission d'un type particulier de nanocristaux semiconducteurs, appelé dots-in-rod, dans lesquels un cœur de séléniure de cadmium (CdSe) est entouré par une coquille en sulfure de cadmium (CdS) de forme allongée. Depuis les année 2000, il est bien connu que les nanocristaux semiconducteurs sont des sources de photons uniques à température ambiante. Cependant, les applications des nanocristaux sont affectées entre autre par deux caractéristiques de leur photoluminescence: le scintillement et l'émission non polarisée. Nous avons montré qu'il est possible de modifier l'émission des dots-in-rod en agissant sur leurs paramètres géométriques, c'est-à-dire le diamètre du cœur ainsi que l'épaisseur et la longueur de la coquille, aboutissant à la suppression du scintillement et à un degré élevé de polarisation linéaire des photons émis. Dans la deuxième partie, la thèse démontre la réalisation des cavités à cristaux photoniques en nitrure de silicium (Si3N4) pour le domaine spectral du visible. Le couplage de ces cavités avec des dot-in-rods a été étudié en régime de couplage faible et nous avons obtenu une modification de l'émission spontanée par effet Purcell. La possibilité d'obtenir le régime de couplage fort dans ce système est aussi discutée du point de vue théorique. Dans la dernière partie du manuscrit nous avons étudié des systèmes semiconducteurs tels que les microcavités et le micropiliers dans lesquels le régime de couplage fort exciton-photon donne naissance aux polaritons. Dans le cas de polaritons confinés, les interactions répulsives entre polaritons peuvent porter à un régime appelé polariton quantum blockade, dans le quel un seul polariton peut être excité dans la structure, ce régime est très prometteur pour la réalisation de sources à photons uniques basées sur les polaritons en cavité. Dans ce travail, nous développons une technique original et flexible basée sur une excitation résonante à deux photons pour attendre le polariton quantum blockade. Enfin, un nouveau régime d'émission appelé two-photon polariton laser est étudié toujours à la technique d'excitation résonante à deux photons.

Abstract:
Diese Arbeit beschäftigt sich mit der Untersuchung der starken Kopplung und Laseremission in Strukturen, die ZnO, ZnCdO oder organische Moleküle als aktives Material enthalten. Die ZnCdO basierten Vielfachquantengräben erreichen ihre Laserschwelle durch optische Ruckkopplung an streuenden Luftlöchern. Diese Emitter nennt man random laser. Die Dynamik ihrer Emission unter quasi-stationären Bedingungen ist der hier gezeigte Fokus. Hoch reproduzierbare Anregungen werden verwendet um sowohl die Dynamik eines einzelnen Beschusses aber auch die Unterschiede verschiedener Anregungen zu untersuchen. Die experimentellen Daten werden durch numerische Simulation qualitativ reproduziert und mit Methoden der Netzwerktheorie interpretiert. Die verbreitetere optische Rückkopplung durch einen Resonator wird in der Untersuchung des Moleküls L4P und seiner Spiro-derivate benutzt. Zwei identische Braggspiegel umschließen die aktive Schicht aus L4P-SP2, das in eine Polymermatrix eingebettet ist, eine Dicke von 12 Mikrometer hat und in einer einzelnen Mode lasert (schwache Kopplung). Durch Verringerung der aktiven Schicht auf die Hälfte der Resonanzwellenlänge wird das System in den Bereich der starken Kopplung gebracht. Eine Rabi-Aufspaltung von 90 meV wird zu beiden vibronischen Resonanzen beobachtet. Die energetische Position in Resonanz zu ZnO macht dieses Molekül zu einem guten Kandidaten für die Fertigung einer hybriden Mikrokavität im Bereich der starken Kopplung. Dies wurde in einer teilweise epitaktisch gewachsenen Mikrokavität angewandt, die aus einem ZnMgO basierten Braggspiegel und sechs Quantengräben besteht. Darauf folgt eine aufgeschleuderte Schicht von L4P in der Polymermatrix. Der Resonator wird mit einem dielektrischen Spiegel fertiggestellt. Tieftemperatur Reflektion zeigt eine deutlichen ausweichen und eine gleichverteilte Mischung der drei Resonanz im mittleren Polaritonzweig.
This thesis presents the investigation of strong coupling and lasing in structures using ZnO, ZnCdO or organic molecules as active material. The ZnCdO based multi quantum well structures reach the lasing threshold by using scattering at air holes as the optical feedback. Such emitters are called random lasers. The dynamics of their emission under quasi-stationary condition is the point of interest presented. Highly reproducible excitations are used to investigate the single shot dynamics and their shot to shot differences. The experimental data is qualitatively reproduced by numerical simulation and interpreted by means of network theory. The more common optical feedback by a cavity is applied in the investigation of the molecule L4P and its spiro-derivatives. Using two identical SiO2/ZrO2 based Bragg reflectors surrounding an active layer of L4P-SP2 in a polymer matrix of approximately 12 microns thickness reached single mode lasing (weak coupling). Reducing the active layer thickness to half the resonance wavelength pushes the system into the strong coupling regime. Angular resolved reflectivity shows the anticrossing of the tuned cavity resonance to two vibronic transitions of the molecule. The Rabi-splitting to both vibronic resonances reaches around 90 meV. The energetic position in resonance to ZnO makes this molecule a promising candidate for a hybrid inorganic/organic microcavity in the strong coupling regime. This is used in a partially epitaxially grown microcavity composed of a ZnMgO based Bragg reflector (alternating layers of different Mg content) and six quantum wells. This is followed by a spincoated layer of L4P in a polymer matrix. The cavity is finished by a dielectric mirror. Low temperature reflectivity shows a clear anticrossing reaching an equal mixing of all resonances for the middle branch.

Abstract:
Cette thèse est consacrée au couplage fort exciton-photon à température ambiante dans les microcavités massives à base de ZnO élaborées par épitaxie par jets moléculaires sur substrat Si(111). Une étude théorique préliminaire montre que le continuum d'absorption des résonances excitoniques est responsable du fort amortissement observé sur la branche haute de polaritons, sans toutefois affecter la branche basse de polaritons. Le couplage fort à température ambiante du mode de cavité ainsi que des modes de Bragg de la microcavité a ensuite été démontré par spectroscopie résolue en angle. De plus, nous observons la présence d'un goulot d'étranglement (bottleneck) sur le mode de Bragg de polaritons. Ce dernier peut être supprimé en faisant varier la densité d'excitons ou la température. Nous comparons nos résultats expérimentaux aux prévisions théoriques faites en vue de l'obtention d'un régime laser à polaritons.

Ce manuscrit de thèse est consacré aux condensats de polaritons dans deux semi-conducteurs à grand gap : GaN et ZnO. La première partie de ce travail se concentre sur l’étude par spectroscopie optique de deux microcavités planaires (une de GaN, l’autre de ZnO) présentant des structures et des propriétés photoniques identiques. Le régime de couplage fort lumière-matière et l’effet laser à polaritons ont pu être observés de 5 K à 300 K pour les deux microcavités. La réalisation de diagrammes de phase a mis en évidence l’impact variable des résonances avec les phonons LO sur l’abaissement du seuil laser. L’étude de la microcavité GaN a été poussée jusqu’à 350 K et nous avons pu démontrer, pour la première fois à cette température, la persistance du couplage fort et du laser à polaritons pour des conditions d’excitations optimales. La deuxième partie de ce travail est focalisée sur des guides d’onde de ZnO. Outre l’observation du régime de couplage fort de 5 K à 300 K, notre étude a pu mettre en exergue un phénomène laser inédit dans cette géométrie : le laser à polaritons horizontal
This manuscript is devoted to polariton condensates in two wide band gap semiconductors: GaN and ZnO. The first part of this work focuses on the study by optical spectroscopy of two planar microcavities (one of GaN, the other of ZnO) sharing the same structure and the same photonic properties. The strong coupling and polariton lasing regime have been observed from 5 K to 300 K in both microcavities. The realization of phase diagrams has pointed out the inconstant impact of resonances with LO phonons on the lowering of the laser threshold. The study of the GaN microcavity has been pushed to 350 K and we have demonstrated, for the first time at this temperature, the persistence of the strong coupling regime and the polariton laser under optimal excitation conditions. The second part of this work is focused on ZnO waveguides. Besides the observation of strong coupling regime from 5 K to 300 K, our study has highlighted a new lasing effect in this geometry: the horizontal polariton laser

Ce manuscrit est consacré à la physique des polaritons dans deux matériaux semiconducteurs à grand gap : ZnO et GaN. Les paramètres polaritoniques de ces matériaux ont été déterminés avec précision grâce à une étude combinant différentes techniques spectroscopiques linéaires et non-linéaires (réflectivité continue, autocorrélation, photoluminescence et mélange à quatre ondes dégénérées). L’interprétation de ces résultats conduit à une meilleure compréhension des processus d’interaction au sein du semiconducteur : le rôle important des interactions polariton-phonon LO dans l’élargissement polaritonique a notamment pu être mis en évidence. Ce travail effectué sur des échantillons massifs est indispensable pour mener au mieux l’étude de l’effet laser à polaritons dans des microcavités présentée dans la seconde partie de ce manuscrit. Pour cette étude, deux microcavités massives semblables, une à base de ZnO l’autre de GaN, ont été réalisées.

Le régime de couplage fort ainsi que l’effet laser à polaritons sont observés jusqu'à température ambiante.

This manuscript is devoted to the physics of polaritons in two wide band gap semiconductor : ZnO and GaN. The polaritonic parameters of these materials have been accurately determined through a study which combines linear and non-linear spectroscopies (continuous reflectivity, autocorrelation, photoluminescence and degenerate four-wave mixing). The interpretation of these results lead to a better understanding of the interaction processes in the semiconductor : the important role played by the polariton-LO phonon interactions in the polaritonic damping is highlighted and particularly for ZnO. This preliminary work on bulk samples is essential for a suitable study of polariton lasing in microcavities like it is presented in the second part of this manuscript. For this study, two similar microcavities, one based on ZnO and another on GaN. The photonic properties of these structures are at the state of the art : they have a good quality factor (Q ≈ 1,000) and have a low photon disorder. The strong coupling regime and the polariton lasing are observed to room temperature. Finally, the establishment of phase diagrams allows to highlight the important role of LO phonons in reduction of the laser threshold

Abstract:
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.

Abstract:
Polariton devices offer multiple advantages compared to conventional semiconductor devices. The bosonic nature of exciton polaritons offers opportunity of realisation of polariton lasers: coherent light sources based on bosonic condensates of polaritons. The final state stimulation of any transition feeding a polariton condensate has been used in many proposals such as for terahertz lasers based on polariton lasers. Furthermore, large coherence lengths of exciton-polaritons in microcavities open the way to realisation of polariton transport devices including transistors and logic gates. Being bosonic spin carriers, exciton-polaritons may be used in spintronic devices and polarisation switches. This chapter offers an overview on the existing proposals for polariton devices.

We also discuss the polarisation properties of the condensate and the superfluid phase transitions for polarised exciton-polaritons. We briefly address the polarization multistability and switching in polariton lasers. Finally, the optical spin-Hall and spin-Meissner effects are described.

Abstract:
This book examines polarity sensitivity—a ubiquitous phenomenon involving expressions such as anybody, nobody, ever, never, and somebody and their counterparts in other languages, with particular focus on Arabic. These expressions belong to different classes such as negative and positive polarity, negative concord, and negative indefinites, which led to examining their syntax and semantics separately. In this book, Ahmad Alqassas pursues a unified approach that relies on examining the interaction between the various types of polarity sensitivity. Treating this interaction is fundamental for scrutinizing their licensing conditions. Alqassas draws on data from Standard Arabic and the major regional dialects represented by Jordanian, Egyptian, Moroccan, and Qatari. The book provides a new perspective on the syntax–semantic interface and develops a unified syntactic analysis for polarity sensitivity. Through the (micro)comparative approach, Alqassas explains the distributional contrasts with a minimal set of universal syntactic operations such as Merge, Move, and Agree, and a fine-grained inventory of negative formal features for polarity items and their licensors. The features are simple invisibles that paint a complex landscape of polarity. The results suggest that syntactic computation of Arabic polarity (externally merged in the left periphery) is subservient to the conceptual–intentional interface. Alqassas argues for last resort insertion of covert negation operators in the CP layer to interpret non-strict NCIs, which is an extra mechanism that serves the semantic interface but adds to the complexity of syntactic computation. Likewise, head NPIs in the left periphery require licensing by operators higher than the tense phrase, adding more constraints on the syntactic licensing.

Abstract:
This book focuses on conceptualizations of lived religion by analysing significant case studies from canonization processes (c. 1240–1450). Geographically it covers Western Europe and one of its aims is to compare Northern and Southern material and customs. ‘Lived religion’ is both a thematic approach and a methodology: a focus on rituals, symbols, and gestures as well as sensitivity to nuances and careful contextualizing of the sources are constitutive elements of the argumentation. Demonic possession was a spiritual state that often had physical symptoms. The main argument developed throughout is, however, that demonic possession was a social phenomenon which should be understood with regard to the community and culture. Each set of sources formed its own specific context, in which demonic presence derived from different motivations, reasonings, and methods of categorization. Rituals, gestures, emotions, and sensory elements in constructing demonic presence reveal negotiations over authority and agency. In the argumentation, the hierarchy between the ‘learned’ and ‘popular’ within religion is contested, as is a strict polarity between individual and collective religious participation. Cases of demonic possession demonstrate how the personal affected the communal, and vice versa, and how they were eventually transformed into discourses and institutions of the Church; that is, definitions of the miraculous and the diabolical. Alterity and inversion of identity, gender, and various forms of corporeality and the interplay between the sacred and diabolical are themes running throughout the volume.

Abstract:
Both rich fundamental physics of microcavities and their intriguing potential applications are addressed in this book, oriented to undergraduate and postgraduate students as well as to physicists and engineers. We describe the essential steps of development of the physics of microcavities in their chronological order. We show how different types of structures combining optical and electronic confinement have come into play and were used to realize first weak and later strong light–matter coupling regimes. We discuss photonic crystals, microspheres, pillars and other types of artificial optical cavities with embedded semiconductor quantum wells, wires and dots. We present the most striking experimental findings of the recent two decades in the optics of semiconductor quantum structures. We address the fundamental physics and applications of superposition light-matter quasiparticles: exciton-polaritons and describe the most essential phenomena of modern Polaritonics: Physics of the Liquid Light. The book is intended as a working manual for advanced or graduate students and new researchers in the field.

Abstract:
This chapter presents the semantics and pragmatics of prosodic focus in alternative semantics. Half a dozen examples are given of empirical phenomena that are to be covered by the theory. Then a syntax marking the locus, scope, and antecedent for focus is introduced. The syntax is interpreted semantically and pragmatically by a presupposition involving alternatives. The alternative sets that are used in the definition are computed compositionally using a recursive definition. Alternatives are also employed in the semantics of questions, and this ties in with the phenomenon of question-answer congruence, where the position of focus in an answer matches questioned positions in the question. A different semantic interpretation for focus is entailment semantics, which uses a generalized entailment condition in place of a condition involving alternatives. The semantic and pragmatic interpretation for contrastive topic uses an additional layer of alternatives. Independent of focus, alternatives are deployed in the semantics of disjunction and of negative polarity items.
