Аннотация: Collective lattice resonances in disordered 2D arrays of spherical Si nanoparticles (NPs) have been thoroughly studied within the framework of the coupled dipole approximation. Three types of defects have been analyzed: positional disorder, size disorder, and quasi-random disorder. We show that the positional disorder strongly suppresses either the electric dipole (ED) or the magnetic dipole (MD) coupling, depending on the axis along which the NPs are shifted. Contrarily, size disorder strongly affects only the MD response, while the ED resonance can be almost intact, depending on the lattice configuration. Finally, random removing of NPs from an ordered 2D lattice reveals a quite surprising result: hybridization of the ED and MD resonances with lattice modes remains observable even in the case of random removing of up to 84% of the NPs from the ordered array. The reported results could be important for rational design and utilization of metasurfaces, solar cells, and other alldielectric photonic devices. (C) 2019 Optical Society of America

Аннотация: Bound states in the continuum (BICs) have attracted considerable research attention due to their infinite quality factor (Q-factor) and extremely localized fields, which drastically enhances light–matter interactions and yields high potential in topological photonics and quantum optics. In this study, the room temperature directional lasing normal to a BIC metasurface is demonstrated with hybrid surface lattice resonances. Compared to the plasmonic nanolasers, the BIC metasurface lasers possess directional radiation and a larger emission volume. The high Q-factor resonance of BIC metasurface overcomes the limitation of a large mode volume in achieving low-threshold lasing. In addition, a design rule is proposed to prevent the occurrence of wavelength shift when the Q-factor changes; thus, the lasing thresholds for different BIC metasurfaces can be compared. In this work, the high localization ability of BICs is used to achieve the low lasing threshold (1.25 nJ) at the room temperature. The “light in–light out” diagram of the aforementioned laser based on simulations and experiments exhibits a large spontaneous emission coupling factor (β = 0.9) and the S-curve. The device developed in this study can be used in various applications, such as quantum emitters, optical sensing, nonlinear optics, and topological states engineering.

Аннотация: Антенны на основе тензорных метаповерхностей – это сравнительно новый тип антенн, появившийся в последнее десятилетие. Они отличаются простой конструкцией, но сложной процедурой синтеза, которая может быть основана на анализе свойств волн в периодических структурах или на основе интерпретации антенны как фазовой голограммы. В связи с новизной этого типа антенн представляет интерес исследование различных методик их синтеза, получение новых экспериментальных результатов и оценка на их основе реально достижимых характеристик таких антенн. Целью работы являлось экспериментальное исследование антенн на основе тензорных метаповерхностей c модулированным поверхностным импедансом, синтезированных по предложенной авторами методике. Для проведения исследований было использовано математическое моделирование, электродинамическое моделирование и измерения макетов антенн в ближней зоне излучения. В результате работы экспериментально подтверждено, что предложенная методика синтеза антенн на основе тензорных метаповерхностей позволяет получать антенны с заданными направлением излучения и поляризацией, которые обладают апертурной эффективностью до 50 %, шириной полосы рабочих частот до 8 % и уровнем кросс-поляризации ниже минус 20 дБ. Результаты измерений антенн хорошо согласуются с электродинамическим расчетом и заданными при синтезе параметрами. Описанный в работе тип антенн и приведенная методика их синтеза перспективны для ряда применений, например в спутниковой и мобильной связи.Antennas based on metasurfaces with tensorial impedance is a relatively new type of antennas appeared in the last decade. They have a simple design, but a complex synthesis procedure. The synthesis procedure can be based on analysis of the properties of waves in periodic structures or on representing the antenna as a phase hologram. Due to the novelty of this type of antennas, researching of various synthesis methods, obtaining new experimental results and on their basis assessment of realistically achievable characteristics is of interest. The purpose of the work was an experimental research of antennas based on metasurfaces with tensorial surface impedance, synthesized according to the method proposed by the authors. To carry out the research, mathematical modeling, electrodynamic modeling, and nearfield measurements of antenna prototypes were used. As a result, it was experimentally confirmed that the proposed tensorial metasurface antennas synthesis method makes it possible to obtain antennas with a given radiation direction and polarization, which have an aperture efficiency of up to 50 %, a bandwidth of up to 8 %, and a cross-polarization level below minus 20 dB. The results of measurements are in a good agreement with the electrodynamic calculation and the parameters specified during the synthesis. The type of antennas described in the work and the given synthesis method, according to the authors, are promising for various applications, for example, in satellite and mobile communications.

Заглавие : Substrate-mediated lattice Kerker effect in Al metasurfaces

Аннотация: Surface lattice resonances (SLRs) emerging in regular arrays of plasmonic nanoparticles (NPs) are known to be exceptionally sensitive to the homogeneity of the environment. It is considered necessary to have a homogeneous environment for engineering narrowband SLRs, while in a half-space environment, SLRs rapidly vanish as the contrast between the refractive indices of the substrate and superstrate increases. From this conventional wisdom, it is apparent that the delicate lattice Kerker effect emerging from SLRs and resonances on constituent NPs should be difficult to achieve in a non-homogeneous environment. Using a rigorous theoretical treatment with multipolar decomposition, we surprisingly find and explain a narrowband substrate-mediated lattice Kerker effect in two-dimensional arrays of Al nanocylinders in a half-space geometry. We propose to use this effect for sensing applications and demonstrate its broad tunability across the UV/Vis wavelength range.

Заглавие : Multipolar lattice resonances in plasmonic finite-size metasurfaces

Аннотация: Collective lattice resonances in regular arrays of plasmonic nanoparticles have attracted much attention due to a large number of applications in optics and photonics. Most of the research in this field is concentrated on the electric dipolar lattice resonances, leaving higher-order multipolar lattice resonances in plasmonic nanostructures relatively unexplored. Just a few works report exceptionally high-Q multipolar lattice resonances in plasmonic arrays, but only with infinite extent (i.e., perfectly periodic). In this work, we comprehensively study multipolar collective lattice resonances both in finite and in infinite arrays of Au and Al plasmonic nanoparticles using a rigorous theoretical treatment. It is shown that multipolar lattice resonances in the relatively large (up to 6400 nanoparticles) finite arrays exhibit broader full width at half maximum (FWHM) compared to similar resonances in the infinite arrays. We argue that our results are of particular importance for the practical implementation of multipolar lattice resonances in different photonics applications.

Аннотация: 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.

Аннотация: This study is devoted to the development and research of multibeam antennas based on anisotropic metasurfaces with one or several feed points. An innovative technique for synthesizing the tensor impedance distribution for the formation of three beams from a radiating metasurface was proposed. Prototypes of the proposed antennas in the Ku-band frequency with one and three feed points were fabricated, and their characteristics were experimentally investigated. The gain of the manufactured multibeam antennas reaches 23 dBi. Good agreement between the results of the numerical simulation and experimental data was achieved, which indicates the reproducibility of the synthesis method in practice. Multibeam antennas on anisotropic metasurfaces can be scaled to high frequencies and effectively used at operating frequencies up to the sub-terahertz range. Such antennas are promising for the development of terrestrial communication infrastructure as 5/6G transmitters and repeaters, as well as for use as a payload of low-orbit satellite systems.

Аннотация: In O-and C-band optical communications, Ge is a promising material for detecting optical signals that are encoded into electrical signals. Herein, we study 2D periodic Ge metasurfaces that support optically induced electric dipole and magnetic dipole lattice resonances. By overlapping Mie resonances and electric dipole lattice resonances, we realize the resonant lattice Kerker effect and achieve narrowband absorption. This effect was applied to the photodetector demonstrated in this study. The absorptance of the Ge nanoantenna arrays increased 6-fold compared to that of the unpatterned Ge films. In addition, the photocurrent in such Ge metasurface photodetectors increases by approximately 5 times compared with that in plane Ge film photodetectors by the interaction of these strong near-fields with semiconductors and the further transformation of the optical energy into electricity.
