AbstractData-driven design approaches based on deep learning have been introduced in nanophotonics to reduce time-consuming iterative simulations, which have been a major challenge. Here, we report the first use of conditional deep convolutional generative adversarial networks to design nanophotonic antennae that are not constrained to predefined shapes. For given input reflection spectra, the network generates desirable designs in the form of images; this allows suggestions of new structures that cannot be represented by structural parameters. Simulation results obtained from the generated designs agree well with the input reflection spectrum. This method opens new avenues toward the development of nanophotonics by providing a fast and convenient approach to the design of complex nanophotonic structures that have desired optical properties.

Nanophotonics use the interaction between light and subwavelength structures to design nanophotonic devices and to show unique optical, electromagnetic, and acoustic properties that natural materials do not have. However, this usually requires considerable expertise and a lot of time-consuming electromagnetic simulations. With the continuous development of artificial intelligence, people are turning to deep learning for designing nanophotonic devices. Deep learning models can continuously fit the correlation function between the input parameters and output, using models with weights and biases that can obtain results in milliseconds to seconds. In this paper, we use finite-difference time-domain for simulations, and we obtain the reflectance spectra from 2430 different structures. Based on these reflectance spectra data, we use neural networks for training, which can quickly predict unseen structural reflectance spectra. The effectiveness of this method is verified by comparing the predicted results to the simulation results. Almost all results maintain the main trend, the MSE of 94% predictions are below 10−3, all are below 10−2, and the MAE of 97% predictions are below 2 × 10−2. This approach can speed up device design and optimization, and provides reference for scientific researchers.

The optimal development of biosensors is a costly and time-consuming task, since an enormous amount of experiments is required. Therefore, the possibility of reusing the biosensors is highly desirable. In this work, a protocol based on the use of formamide for the regeneration of nanophotonic biosensors used for oligonucleotides detection is presented. This protocol was carried out online using the microfluidic system used to drive the target samples to the nanophotonic biosensor, thus allowing the possibility of running several experiments in a row using the same biosensor.

Abstract In this work, we demonstrate the possibility of using mechanical Scanning probe lithography (m-SPL) for fabricating nanophotonic devices based on multilayered transition metal dichalcogenides (TMDCs). By m-SPM, we created a nanophotonic resonator from a 70-nm thick MoSe2 flake transferred on Si/Au substrate. The optical properties of the created structure were investigated by measuring microphotoluminescence. The resonator exhibits four resonance PL peaks shifted in the long-wavelength area from the flake PL peak. Thus, here we demonstrate that m-SPL is a high-precision lithography method suitable for creating nanophotonic devices based on multilayered TMDCs.

Being able to manipulate light and confine it to small length scales have a multitude of applications in modern technology. Predicting the behavior of nanophotonic devices and the realization of new ones will greatly benefit from insights offered by analytical calculations and numerical modeling. In this paper, we elucidate the fundamental electromagnetic responses of materials and introduce a versatile technique, called transfer matrix method, in modeling the behavior of nanoscale heterostructures. Its application in novel photonic devices such as semiconductor microcavities and surface plasmon resonance sensors will be demonstrated.

The topological nanophotonic wavelength router, which can steer light with different wavelength signals into different topological channels, plays a key role in optical information processing. However, no effective method has been found to realize such a topological nanophotonic device. Here, an on-chip topological nanophotonic wavelength router working in an optical telecom band is designed based on a topology optimization algorithm and experimentally demonstrated. Valley photonic crystal is used to provide a topological state in the optical telecom band. The measured topological wavelength router has narrow signal peaks and is easy for integration. This work offers an efficient scheme for the realization of topological devices and lays a foundation for the future application of topological photonics.

The energy consumption of manycore architectures is dominated by data movement, which calls for energy-efficient and high-bandwidth interconnects. To overcome the bandwidth limitation of electrical interconnects, integrated optics appear as a promising technology. However, it suffers from high power overhead related to low laser efficiency, which calls for the use of techniques and methods to improve its energy costs. Besides, approximate computing is emerging as an efficient method to reduce energy consumption and improve execution speed of embedded computing systems. It relies on allowing accuracy reduction on data at the cost of tolerable application output error. In this context, the work presented in this article exploits both features by defining approximate communications for error-tolerant applications. We propose a method to design realistic and scalable nanophotonic interconnect supporting approximate data transmission and power adaption according to the communication distance to improve the energy efficiency. For this purpose, the data can be sent by mixing low optical power signal and truncation for the Least Significant Bits (LSB) of the floating-point numbers, while the overall power is adapted according to the communication distance. We define two ranges of communications, short and long, which require only four power levels. This reduces area and power overhead to control the laser output power. A transmission model allows estimating the laser power according to the targeted BER and the number of truncated bits, while the optical network interface allows configuring, at runtime, the number of approximated and truncated bits and the laser output powers. We explore the energy efficiency provided by each communication scheme, and we investigate the error resilience of the benchmarks over several approximation and truncation schemes. The simulation results of ApproxBench applications show that, compared to an interconnect involving only robust communications, approximations in the optical transmission led to up to 53% laser power reduction with a limited degradation at the application level with less than 9% of output error. Finally, we show that our solution is scalable and leads to 10% reduction in the total energy consumption, 35× reduction in the laser driver size, and 10× reduction in the laser controller compared to state-of-the-art solution.

Today's commodity camera systems rely on compound optics to map light originating from the scene to positions on the sensor where it gets recorded as an image. To record images without optical aberrations, i.e., deviations from Gauss' linear model of optics, typical lens systems introduce increasingly complex stacks of optical elements which are responsible for the height of existing commodity cameras. In this work, we investigate flat nanophotonic computational cameras as an alternative that employs an array of skewed lenslets and a learned reconstruction approach. The optical array is embedded on a metasurface that, at 700 nm height, is flat and sits on the sensor cover glass at 2.5 mm focal distance from the sensor. To tackle the highly chromatic response of a metasurface and design the array over the entire sensor, we propose a differentiable optimization method that continuously samples over the visible spectrum and factorizes the optical modulation for different incident fields into individual lenses. We reconstruct a megapixel image from our flat imager with a learned probabilistic reconstruction method that employs a generative diffusion model to sample an implicit prior. To tackle scene-dependent aberrations in broadband , we propose a method for acquiring paired captured training data in varying illumination conditions. We assess the proposed flat camera design in simulation and with an experimental prototype, validating that the method is capable of recovering images from diverse scenes in broadband with a single nanophotonic layer.

The aim of this study was to develop new soft contact lens (SCL) materials which would, after recommended and existing machining processes, improve surface roughness. Nanomaterials (fullerene, fullerol and methformin hydroxylate fullerene) were incorporated into commercial material for SCL (SL38) based on PHEMA, which were derived by the technology in the production lab of the company Soleko (Milan, Italy). Nanophotonic SCLs (SL38-A, SL38-B, SL38-C, respectively) were produced in the company Optix (Belgrade, Serbia) from the obtained materials. For the surface characterization of SCLs, AFM analysis and lacunarity method were performed. The results showed that for the SL38-B average roughness value is lower than those of SL38-A and SL38. The topography parameters of SL38-C were between the parameters of SL38-A and SL38-B. Lacunarity analysis of AFM images confirmed that SCLs surface state should belong to either group of adequate (slanted p-diagram) or inadequate (contorted p-diagram) roughness concerning tear film stability. Nanophotonic SCL SL38-C exibits more acceptable performance considering SCL surface functional behavior as compared to other SCLs. The positive result of incorporating nanomaterials into basic material for SCL is better quality of the nanophotonic SCLs surfaces. On the bases of these experiments, the assumption that incorporation of fullerene derivate will not increase surface roughness parameters is confirmed.

Polycyclic aromatic hydrocarbons (PAHs) are the widespread environmental contaminants that can be found in atmosphere, water, soil, sediment and organisms. Among most dangerous PAHs is benzo[a]pyrene (BP). The effects of BP on health are: short-term when people are exposed to it at levels above the maximum contaminant level (MCL) (0.2 ppm) for relatively short periods of time leading to red blood cells damage, anemia ect; suppression of immune system and long-term, when human beings are exposured do BP influence at levels above the MCL namely effects on reproducibility and high probability of cancer illnesses. There are known methods for PAHs detection, such as chromatography, immuno-chemistry, biological and chemical ones. However, they have several disadvantages, including high cost, duration and complexity of the analysis procedure, the high detection limit and low selectivity. So at present a development of a new method of PAHs detection based on modern technologies and materials such as nanotechologies and nanomaterials. Belonging to above mentioned is nanophotonic method of PAHs assay. Nanophotonic method for PAHs detection in particular BP in water is a combination of electrochemical and electrochemiluminescence analysis with the application of nanomaterials and nanotechnologies. This method can be carried out using nanophotonic sensor based on nanomaterials such as semiconductor quantum dots (QDs).

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental agents commonly believed to contribute significantly to human cancers pathologies. PAHs are formed in the process of incomplete combustion of organic material and are found widely in the environment, for example, in water, food, soil etc. so human exposure to PAHs is unavoidable. Like many other carcinogens, polycyclic aromatic hydrocarbons are metabolized enzymatically to various metabolites, of which some are highly reaction active. One of the most dangerous organic PAHs carcinogens is benzo[a]pyrene (BP). There are known methods for PAHs detection in water objects, such as chromatography, immuno-chemical, biological and chemical ones. However, they have several disadvantages, including high cost, duration and complexity of the analysis procedure, high detection limit, low selectivity and some others. So at present a development of new methods of PAHs detection based on modern technologies and materials such as nanotechologies and nanomaterials is a rather relevant and important task.

Anthropogenic pollution of environmental water is a huge problem for humanity today as it leads to an increase of incurable diseases. For example, the penetration into the organism of organic carcinogens such as polycyclic aromatic hydrocarbons (PAHs) can lead to the development of cancer tumors. Among PAHs the most dangerous is 3,4-benzopyrene (BP). There are a number of analytical methods for BP detection such as chromatographic, immuno-chemical, spectroscopic, luminescent and biological methods. But these methods beside their advantages have a number of significant shortcomings such as high detection limit (immuno-chemical and biological method), insufficient selectivity of PAHs detection, complexity and duration of sample preparation and analysis, high cost of device. Therefore development of new methods and tools for PAHs detecting using modern nanotechnology and nanomaterials remains urgent. So this work is devoted to the development of nanophotonic method and sensor device construction for the PAH in particular BP detection in water environment objects. Nanomaterials such as spherical quantum dots (QDs) are perspective object of nanophotonics can be used for development of optical sensors as sensor’s detector elements. They have a high luminescence quantum yield, possibility of optical and non-optical excitation, narrow luminescence spectrum and its wavelength dependence on the QDs diameter, high selectivity. This defined the perspective of their use instead of the well known organic luminophores.

The aim of this thesis is to develop a technique which can be used in the reliable modelling, design and optimisation of practical suboptical wavelength sized photonic/plasmonic devices, which may involve arbitrary geometries on various scales. The technique involves the application of numerical electromagnetic simulation led by theoretical knowledge and physical insight to determine, design and optimise the operating mechanism of such devices. The work in this thesis contains a variety of problems/devices which involve arbitrary structures of different scales. This poses difficulties in both the fabrication and the modelling aspects of the design. The problems range in difficulty from those which can be simply and perfectly described via an analytical solution, to those which would be impractical to design using any other technique. The nature of the problems considered, i.e. the complicated geometry and the range of scales, necessitates the use of a flexible modelling technique. Finite Element Method (FEM) was found to be a valuable tool in the design and optimisation of the devices throughout this thesis, owing its success mainly to its versatility and flexible meshing abilities which allowed its operation in different length scales in an efficient manner. Three nanophotonic/plasmonic devices are considered in an effort to demonstrate the implementation and the application of the developed technique. The devices considered in this thesis demonstrate different challenges in the modelling and design while being of considerable interest in their own right as nanostructures for sensing and measurement. These devices are: A self-calibrated plasmon sensor, a plasmon resonator and an ultrahigh frequency optical acoustic surface wave detector. Whilst the first two devices are important as an application of plasmonics, the third device links the mechanical and optical processes together.

Benzo[a]pyrene (BaP) is representative of polycyclic aromatic hydrocarbons (PAHs) family, the substance of the first hazard class. In an environmental, BaP accumulates mainly in a soil and less in a water. It comes from soil to plants and human tissues and continues to move on in the food chain in living organisms where at each stage the BaP concentration is increasing sufficiently. To human organism BaP can come through skin, respiratory organs, digestive system and transplacental infections. Besides that BaP is the most typical chemical carcinogen in environmental, it is dangerous to humans even at low concentrations, since its metabolites are mutagenic and highly carcinogenic and has the property for bioaccumulation. Being chemically relatively stable, BaP can migrate for a long time from one object to another. As a result, many objects and process in the environmental objects which do not have the ability to synthesize the BaP, are the secondary sources of its production. Content control of BaP in environmental can be accomplished by different assay among which the most wide-spread is liquid chromatography. Known methods possess both positive and negative characteristics the last are connected with assay complexity, not allowing of their used in a field conditions, duration, high cost. So new technologies especially based on nanotechnologies and nanomaterials are in great demand both for BaP and other hazardous organic PAHs compounds. Having in mind that BaP as most of PAH has high fluorescence yield in visible spectrum and is capable to emit electrogenerated chemiluminescence (ECL), it is quite possible to use this well-known assay method for both direct and indirect definition [1]. At the same time mentioned ECL methods of BaP definition provide not enough low limit of detection (LOD). Using luminescent nanomaterials such as semiconductor quantum dots (SCQD) as highly efficient detector elements in appropriate nanophotonic sensor can provide assay for BaP detection in surrounding objects water in the first turn with rather low LOD (10 nmol/l). The proposed combined photonic (electrochemiluminescent), nanotechnology (sensor’s electrode modification) and electrochemical (analytical signal excitation) techniques are possessing a number of advantages which are discussed in the given paper.

La plasmonique basée sur les matériaux 2D est un domaine en plein essor dans la photonique, avec des implications technologiques potentielles révolutionnaires dans des domaines aussi variés que le diagnostic, l'énergie et la communication. Le graphène, un matériau 2D unique et doté d'excellentes propriétés plasmoniques, est une alternative prometteuse aux métaux nobles conventionnels dans le domaine de la plasmonique, notamment en raison de ses propriétés accordables en fréquence. Le graphène est modélisé dans cette thèse comme une feuille conductrice infiniment mince dans le cadre des éléments finis (vectoriels) de Galerkin, par opposition aux modèles plus conventionnels où la feuille de graphène est considérée comme ayant une épaisseur finie. Une seconde étude 2D rigoureuse du comportement du champ électromagnétique le long de la direction de propagation dans un guide d'ondes ouvert est réalisée en modélisant le graphène comme un diffuseur (1D) qui agit comme une perturbation locale au guide. Enfin, l'important décalage d’indice effectif qui existe entre le mode du guide d'ondes dielectrique et le mode plasmonique du graphène altère le couplage. Pour surmonter ce problème, un coupleur est conçu à l'aide du formalisme direct en champ diffracté développé. Des études approfondies du phénomène de battement observé dans le coupleur sont également réalisées. Plusieurs études impliquant les différents ordres de diffraction du réseau coupleur, l'épaisseur du guide d'ondes, etc. sont menées. Les paramètres du coupleur sont ensuite optimisés pour obtenir un coupleur à réseau compact et intégré à base de graphène dont l'efficacité atteint 80% à dans l’infrarouge<br>Plasmonics based on 2D materials is a burgeoning field in photonics with potential groundbreaking technological implications for diagnostics, energy and data communication. Graphene, a unique 2D material with excellent plasmonic properties is a promising alternative to conventional noble metals in plasmonics notably due to its tunable properties. Graphene is modelled in this thesis as an infinitesimally thin current-carrying sheet in a fully vectorial finite element Galerkin framework as opposed to more conventional models where graphene is considered to be of finite thickness. A rigorous study of the behaviour of the electromagnetic field along the propagation direction in an openridge waveguide is carried out by modelling graphene as a 1D conductive scatterer which acts as a local perturbation. The scattering model is verified through a full energy balance in different geometries. The large momentum mismatch that exists between the waveguide mode and the graphene plasmon mode in a graphene-based waveguide severely alters the coupling between these two modes. To overcome this, a coupler is designed using the developed scattering field formalism. Elaborate studies of the beating phenomenon observed in the coupler are performed. The designed waveguide coupler is apt for graphene of lengths equal to or shorter than the order of the wavelength. Several studies involving the various diffraction orders of the grating coupler, waveguide thickness, etc. are conducted. The parameters of the coupler are then optimized to yield a compact and integrated graphene-based grating coupler of efficiency as high as 80% in the infrared region

Interest in nanophotonics continues to grow as integrated optics provides an affordable platform for areas like telecommunications, quantum information processing, and biosensing. Designing and characterizing integrated photonics components and circuits, however, remains a major bottleneck. This is especially true when complex circuits or devices are required to study a particular phenomenon.To address this challenge, this work develops and experimentally validates a novel machine learning design framework for nanophotonic devices that is both practical and intuitive. As case studies, artificial neural networks are trained to model strip waveguides, integrated chirped Bragg gratings, and microring resonators using a small number of simple input and output parameters relevant to designers. Once trained, the models significantly decrease the computational cost relative to traditional design methodologies. To illustrate the power of the new design paradigm, both forward and inverse design tools enabled by the new design paradigm are demonstrated. These tools are directly used to design and fabricate several integrated Bragg grating devices and ring resonator filters. The method's predictions match the experimental measurements well and do not require any post-fabrication training adjustments.

Deep learning has become a vital approach to solving a big-data-driven problem. It has found tremendous applications in computer vision and natural language processing. More recently, deep learning has been widely used in optimising the performance of nanophotonic devices, where the conventional computational approach may require much computation time and significant computation source. In this chapter, we briefly review the recent progress of deep learning in nanophotonics. We overview the applications of the deep learning approach to optimising the various nanophotonic devices. It includes multilayer structures, plasmonic/dielectric metasurfaces and plasmonic chiral metamaterials. Also, nanophotonic can directly serve as an ideal platform to mimic optical neural networks based on nonlinear optical media, which in turn help to achieve high-performance photonic chips that may not be realised based on conventional design method.

Abstract Optical cavities or resonators having dimensions of the order of cube of the wavelength, are introduced with the definitions of DOM, mode volume, quality factor, finesse, and loss mechanisms in general. The simplest resonator structures, the FP resonator, Bragg gratings and mirrors, and ring resonators and their characteristics are presented next. Resonators working with whispering gallery modes, different structures used, and both ray-optic and electromagnetic theories to understand their operations are also discussed. The formation of photonic band gap in photonic crystal is illustrated by solving wave equation in a 1D periodic structure. The concepts are extended to 2D and 3D periodic structures, giving representative structures, typical dispersion relations, examples of photonic band gaps, and the methods to form waveguides. The micropillar structure is discussed in detail. Finally, a summary of different resonator structures, method of light confinement, values of Q, and sources are given.
