Аннотация:
В статье описан перспективный способ получения водорода – фотоэлектрохимическое расщепление воды. Этот подход сочетает непосредственное использование солнечной энергии и низкую стоимость производства фотоэлектрохимических ячеек из широко распространенных на Земле полупроводниковых материалов. Последние достижения в конструировании таких ячеек включают наноструктурирование полупроводниковых электродов плазмонными материалами.This article describes a promising hydrogen formation method, namely the photoelectrochemical water splitting. This approach combines the direct use of solar energy and low production cost of photoelectrochemical cells using the widely used semiconductor materials. The latest advances in such cell design include nanostructuring of the semiconductor electrodes with plasmonic materials.

Аннотация:
Топологический изолятор – это материал, одновременно проявляющий свойства проводника на поверхности и изолятора в объеме. Игрой Руднера называют упрощенную модель топологического изолятора, экспериментально реализованную на двумерных фотонных решетках и описывающуюся как клеточный автомат, подобный игре жизнь Конвея. Трехцветным клеточным автоматом называют регулярную решетку ячеек, каждая из которых окрашена в один из трех цветов и задано правило перекрашивания ячеек. В данной работе два цвета клеточного автомата соответствуют отсутствию и наличию фотона в резонаторе, а третий цвет – границе области. Игра Руднера обобщается на случай трехмерного массива оптических резонаторов и демонстрируются определяющие свойства топологического изолятора. Вводится класс клеточных автоматов, сохраняющих границу и количество фотонов, а также нулевую групповую скорость для фотонов, удаленных от поверхности. Ожидаются физические реализации в фотонике, электронике, механике и акустике.A topological insulator is a material that simultaneously exhibits the properties of a conductor on the surface and an insulator in volume. Rudner's game is a simplified model of a topological insulator, experimentally implemented on two-dimensional photonic lattices and described as a cellular automaton similar to Conway's game of life. A three-color cellular automaton is a regular lattice of cells. Each cell takes one of three colors according to the specified cell recoloring rule. In this work, two colors of the cellular automaton correspond to the absence and presence of a photon in the resonator, and the third color corresponds to the boundary of the region. The Rudner game is generalized to the case of a three-dimensional array of optical cavities and the defining properties of a topological insulator are demonstrated. A class of cellular automata is introduced that preserve the boundary and the number of photons, as well as zero group velocity for photons far from the surface. Physical realizations are expected in
photonics
, electronics, mechanics, and acoustics.

Аннотация:
Развита теория генерации второй гармоники фемтосекундных лазерных импульсов в 3D периодических нелинейных фотонных кристаллах. Получено выражение для спектральной интенсивности второй гармоники для спектрально-ограниченных и чирпированных фемтосекундных лазерных импульсов. Показана возможность нелинейного мультиплексирования генерируемого излучения и формирования дискретного углового спектра генерируемого излучения. Продемонстрирована роль дисперсии групповых скоростей в формировании частотно-углового спектра генерируемого излучения. The theory of second harmonic generation of femtosecond laser pulses in three-dimensional periodic nonlinear photonic crystals is developed. The expression for spectral intensity of the second harmonic for transform-limited and chirped femtosecond laser pulses is obtained. Possibility of nonlinear multiplexing and discrete angular spectrum formation has been demonstrated. The role of group velocity mismatch in formation of frequency-angular spectra of generated radiation is shown.

Аннотация:
The polarizing spectroscopy techniques in visible range optics have been used since the beginning of the 20th century to study the anisotropy of crystals based on birefringence and optical activity phenomena. On the other hand, the phenomenon of X-ray optical activity has been demonstrated only relatively recently. It is a selective probe for the element-specific properties of individual atoms in non-centrosymmetric materials. We report the X-ray Natural Circular Dichroism (XNCD) imaging technique which enables spatially resolved mapping of X-ray optical activity in non-centrosymmetric materials. As an example, we present the results of combining micro-focusing X-ray optics with circularly polarized hard X-rays to make a map of enantiomorphous twinning in a multiferroic SmFe3(BO3)4 crystal. Our results demonstrate the utility and potential of polarization-contrast imaging with XNCD as a sensitive technique for multiferroic crystals where the local enantiomorphous properties are especially important. In perspective, this brings a novel high-performance method for the characterization of structural changes associated with phase transitions and identification of the size and spatial distribution of twin domains.

Аннотация:
Electrodynamical interaction between excited NPs is rather universal and allows formation of wide variety of nanostructures both of homo- and heterogeneous content. Experimental results are obtained for CdTe QDs with the excitonic resonance at 520 nm. Six different samples of the same colloid solution were irradiated at wavelengths from 540 to 570 nm. Modifications of absorption spectra of solutions after irradiation was detected, being most prominent at 555 and 560 nm irradiation wavelengths. Analysis of spectra shows that up to 47% of QDs were assembled into pairs. Therefore, possibility of precise QDs manipulation via laser-induced electrodynamical interaction is demonstrated.

Аннотация:
The dynamic steering of a beam reflected from a photonic structure supporting Tamm plasmon polariton is demonstrated. The phase and amplitude of the reflected wave are adjusted by modulating the refractive index of a transparent conductive oxide layer by applying a bias voltage. It is shown that the proposed design allows for two-dimensional beam steering by deflecting the light beam along the polar and azimuthal angles.

(''Своб.индексиров.''): photonic crystal--nanocomposite--epsilon near zero material--tamm plasmon polariton
Аннотация:
The spectral properties of a one-dimensional photonic crystal bounded by a resonant absorbing nanocomposite layer with the near-zero permittivity have been studied. The problem of calculating the transmittance, reflectance, and absorptance spectra of such structures at the normal and oblique incidence of light has been solved. It is shown that, depending on the permittivity sign near zero, the nanocomposite is characterized by either metallic or dielectric properties. The possibility of simultaneous formation of the Tamm plasmon polariton at the photonic crystal/metallic nanocomposite interface and the localized state similar to the defect mode with the field intensity maximum inside the dielectric nanocomposite layer is demonstrated. Specific features of field localization at the Tamm plasmon polariton and defect mode frequencies are analyzed. © 2018 by the authors.

Аннотация:
The circular polarization of light flips its handedness after a conventional metallic mirror reflection. Therefore, a polarization-preserving metasurface is a crucially important element in a series of chiral photonic structures. They include tunable cholesteric LCs and anisotropic photonic crystals. Chiral structures are rich in interfacial localized modes including Tamm states. In this report, coupled modes formed as a result of the interaction between two chiral optical Tamm states or a chiral optical Tamm state and a chiral Tamm plasmon polariton are analytically and numerically investigated. It is shown that the effective control of coupled modes can be carried out by changing the pitch of the cholesteric and the angle between the optical axis of the cholesteric and the polarization-preserving anisotropic mirror. The influence of the metasurface period on the spectral characteristics of coupled modes is investigated. The possibility of realizing a bound state in the continuum of the Friedrich–Wintgen type, resulting from the destructive interference of coupled modes, which leads to the collapse of the resonance line corresponding to the chiral optical Tamm state, has been demonstrated.

(''Своб.индексиров.''): nanoparticle--titanium nitride--surface plasmon polariton--plasmon waveguide--refractory plasmonics
Аннотация:
We propose to utilize titanium nitride (TiN) as an alternative material for linear periodic chains (LPCs) of nanoparticles (NPs) which support surface plasmon polariton (SPP) propagation. Dispersion and transmission properties of LPCs have been examined within the framework of the dipole approximation for NPs with various shapes: spheres, prolate and oblate spheroids. It is shown that LPCs of TiN NPs support high-Q eigenmodes for an SPP attenuation that is comparable with LPCs from conventional plasmonic materials such as Au or Ag, with the advantage that the refractory properties and cheap fabrication of TiN nanostructures are more preferable in practical implementations compared to Au and Ag. We show that the SPP decay in TiN LPCs remains almost the same even at extremely high temperatures which is impossible to reach with conventional plasmonic materials. Finally, we show that the bandwidth of TiN LPCs from non-spherical particles can be tuned from the visible to the telecommunication wavelength range by switching the SPP polarization, which is an attractive feature for integrating these structures into modern photonic devices.

Аннотация:
The anodic TiO2 photonic crystals evoke great interest for application as photocatalytic media due to high absorption of light resuling from their specific structure. In this work, the optical properties of the photonic crystal based on a bamboo-type TiO2 nanotube with a metallic coating are analyzed theoretically by the finite-difference time-domain method. The occurrence of Tamm plasmons that appears as a peak in the absorption spectrum is predicted. A Tamm plasmon polariton is a localized state of light excited at the boundary of two highly reflective media, a metal and a Bragg reflector. The integral absorption of the gold-, titanium-, and titanium nitride-coated photonic crystals in the wavelength range of 450–600 nm is calculated. It is established that the titanium nitride-coated structure exhibits the maximum integral absorption.

Аннотация:
In this work we show a preparation technique of Co2FeSi full-Heusler alloy thin films on silicon-on-insulator (SOI) substrates, employing rapid thermal annealing (RTA). The films of the Co2FeSi alloy were formed by a silicidation reaction, caused by RTA, between the ultrathin SOI (001) layer and the Fe/Co layers deposited on it. It is assumed that this technology is compatible with the process of formation of a half-metal source-drain in an advanced CMOS and SOI technology and will be applicable for the manufacture of a source-drain of a field-effect transistor. Schottky barrier field-effect transistors (FET) with a back-gate, based on silicon nanowires with source and drain of a Co2FeSi film, synthesized on an SOI substrate, were manufactured. The transport properties of the device were investigated.

Аннотация:
Backward electromagnetic waves are extraordinary waves with contra-directed phase velocity and energy flux. Unusual properties of the coherent nonlinear optical coupling of the phase-matched ordinary and backward electromagnetic waves with contra-directed energy fluxes are described that enable greatly-enhanced frequency and propagation direction conversion, parametrical amplification, as well as control of shape of the light pulses. Extraordinary transient processes that emerge in such metamaterials in pulsed regimes are described. The results of the numerical simulation of particular plasmonic metamaterials with hyperbolic dispersion are presented, which prove the possibility to match phases of such coupled guided ordinary and backward electromagnetic waves. Particular properties of the outlined processes in the proposed metamaterial are demonstrated through numerical simulations. Potential applications include ultra-miniature amplifiers, frequency changing reflectors, modulators, pulse shapers, and remotely actuated sensors.

Аннотация:
The possibility of light-controllable formation of heterogeneous nanostructures containing resonant metallic and semiconductor nanoparticles is considered. Interaction energy between light-induced dipole polarization of nanoparticles at modest light intensity can be much more than the thermal motion energy. The configuration of self-assembled nanostructure can be controlled by the frequency and polarization of the light.

Аннотация:
Quasibound state in the continuum (quasi-BIC) is a long-lived state with a high quality factor (Q factor). Here quasi-BICs in nematic liquid crystal (LC) layer embedded between a distributed Bragg reflector (DBR) and a metal layer are studied. First, a special class of true BICs between the DBR and the metal film with field localization provided by the Brewster transverse electric (TE) reflection in the DBR is experimentally demonstrated. It is demonstrated that the Q factor of the quasi-BIC can be tuned by the LC optical axis rotation in a wide range being only restricted by metal losses. The change of coupling with the radiation channel leads to a critical coupling condition, providing a total absorption of incident light. The acquired quasi-BIC resonance is extremely sensitive to the temperature due to the narrow nematic temperature range of the LC. The quasi-BIC transforms to BIC at the LC-isotropic clearing point, due to closing of the radiation channel.

Аннотация:
The possibility of creating a polarization-sensitive absorber on the basis of the splitting of a Tamm plasmon polariton at the interface between a metallic film and an anisotropic nanocomposite layer conjugated with a photonic crystal is theoretically predicted. The effect of geometrical parameters on the optical absorption spectra under the critical coupling conditions is discussed. It is shown that, changing the polarization of the radiation falling onto the structure along its normal, one can control the absorption at the Tamm plasmon polariton wavelength.

Аннотация:
It is shown that features of light propagation in plant leaves depend on the long-range ordering in chloroplasts and spectral characteristics of pigments. It is established that, allowing for the dispersion of chlorophyll’s absorption spectrum, the photonic density of states grows and the spectral peak shifts to the efficient photosynthesis wavelength range, enhancing the probability of photosynthesis.
