PMMA opal -- Photonic crystal -- Electron microscopy -- Angular resolved reflective spectroscopy
Аннотация: PMMA opal crystal was prepared by a simple hybrid method, which includes sedimentation, meniscus formation and evaporation. We investigated three surfaces of this crystal by angle-resolved reflective light spectroscopy and SEM study. The angle-resolved reflective measurements were carried out in the 400–1100 nm range. We have determined the high-quality ordered surface of the crystal region. Narrow particle size distribution of the surface has been revealed. The average particle diameter obtained with SEM was nearly 361 nm. The most interesting result was that reflectivity of the surface turned out up to 98% at normal light incidence. Using a fit of dependences of the maximum reflectivity wavelength from an angle based on the Bragg–Snell law, the wavelength of maximum 0° reflectivity, the particle diameter and the fill factor have been determined. For the best surface maximum reflectivity wavelength of a 0° angle was estimated to be 869 nm. The particle diameter and fill factor were calculated as 372 nm and 0.8715, respectively. The diameter obtained by fitting is in excellent agreement with the particle diameter obtained with SEM. The reflectivity maximum is assumed to increase significantly when increasing the fill factor. We believe that using our simple approach to manufacture PMMA opal crystals will significantly increase the fabrication of high-quality photonic crystal templates and thin films

    Anomalous spectral shift of o-modes in multilayer photonic structure induced by homeotropic–homeoplanar transition in chiral–nematic defect layer / V. A. Gunyakov, V. S. Sutormin, I. V.

   Перевод заглавия: Аномальный спектральный сдвиг о-мод в мультислойной фотонной структуре индуцированный переходом от гомеотропной к гомеопланарной конфигурации в хиральном нематическом дефектном слое
Кл.слова (ненормированные):
liquid crystal -- hybrid aligned cholesteric -- ionic surfactant -- multilayer photonic structure -- geometric phase
Аннотация: A chiral nematic is embedded between multilayer mirrors to obtain voltage-inducible polarized resonance spectra. Initially, the nematic director is uniformly oriented perpendicular to the mirrors’ surfaces because the chiral nematic helix is completely untwisted due to the homeotropic boundary conditions specified by the adsorbed cations. Then, a voltage is applied to remove the layer of surface-active cations from the input mirror. The obtained twisted homeoplanar configuration has a helix pitch exceeding the layer’s thickness. The twisting leads to the anomalous blue shift of the o-modes in the transmittance spectrum of the photonic structure. This blue shift can be effectively compensated by repulsion of spectral peaks as a result of mode coupling in the vicinity of the virtual avoided crossing point. The experimental results obtained are confirmed numerically using the 4 ˣ 4 transfer matrix method and explained with the contribution of a geometric phase.

photonic crystal -- nanocomposite -- epsilon near-zero material -- Tamm plasmon polariton
Аннотация: 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.

Two types of localized states in a photonic crystal bounded by an epsilon near zero nanocomposite / R. G. Bikbaev, S. Y. Vetrov, I. V. Timofeev // Photonics. - 2018. - Vol. 5, Is. 3. - Ст. 22, DOI 10.3390/photonics5030022. - Cited References: 53 . - ISSN 2304-6732

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: A top-down nanofabrication approach was used to obtain silicon nanowires from silicon-on-insulator wafers using direct-write electron beam lithography and plasma-reactive ion etching. Fabricated with designed pattern silicon nanowires are 0.4, 0.8, 2 μm in width and 100 nm in height. The devices can be applied in future medical diagnostic applications as novel biosensors with detection principle based on the changes in electrical characteristics of the silicon nanowires functionalized with thiol-containing molecules.

Dipole-dipole interaction -- Laser field -- Brownian dynamics -- Self-assembly of nanostructures -- Colloidal crystals
Аннотация: Self-assembly of nanoparticles under the action of laser field can be an universal method for the formation of nanostructures with specific properties for application in sensorics and nanophotonics. For prognosis of the self-assembly processes, the model of movement of an ensemble of nanoparticles in a viscous media under the action of laser radiation with the account for interaction of laser-induced polarizations and Brownian dynamics is developed. This model is applied to the investigation of the self-assembly process of a triple of nanoparticles into three-particle structure with a predetermined geometry.Two specific cases of formation of nanostructure from a preliminarily formed pair of particles are studied: either for the pair fixed in space or from the unfixed pair of nanoparticles. The geometry of resulting nanostructures is shown to be determined by the polarization direction of laser radiation and the laser wavelength. Under proper choice of these parameters the formation of structures is shown to be highly efficient. E. g., maximum probability of structures formation is as hig as 36–46% per single laser pulse of 10 ns duration. © 2019 Elsevier B.V.

BLUE-GREEN FLUORESCENCE
Аннотация: Epicuticular waxes are a multifunctional interface between a plant and the environment. In this paper wheat leaves wax has been studied. Wax isolation was carried out using the method of gradual freezing in water followed by slow thawing. The morphology of the samples obtained was observed with a Hitachi SU3500 electron microscope. The structure period is determined by the nanotubes diameter which equals 150-200 nm. Random orientation of their long axes in the layer allows using a one-dimensional model to calculate the transmission spectrum of a photonic crystal with the help of the transfer matrix method. While making the calculations a defect that may be caused by possible interlayer heterogeneity also must be taken into account. Numerical modeling made it possible to identify the stop zone and the defective mode. Intense fluorescence appears in the optical area of the wax layer under ultraviolet radiation, thus increasing the efficiency of photosynthesis.

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.
