A white laser with chirped photonic crystals
A. H. Gevorgyan, N. A. Vanyushkin, I. M. Efimov
We report the results on theoretical investigation about possible simultaneous laser generation in all, closely spaced modes of chirped photonic crystals layer in all visible regio…
And again, about lasing threshold, light localization, and density of states
N. A. Vanyushkin, A. H. Gevorgyan
We investigated numerically the relationship between the lasing threshold, the density of states (DOS), and field localization in 1D photonic crystals (PC) for off-axis laser actio…
Defected photonic crystal-based sensor with enhanced performance
I. M. Efimov, N. A. Vanyushkin, A. H. Gevorgyan
We propose an improved structure of an optical biosensor based on a photonic crystal (PC) with a defect layer (DL), which can detect the concentration of SARS-CoV-2 in water by def…
Polarometric Method of Plasma Diagnostics
Koryun B. Oganesyan, Krzysztof Dzierdzega, Peter Kopcansky
The polarization plane rotation angle of probe signal in plasma is calculated. The estimates of the residual gas average density and the average magnitude of the magnetic field in…
Optical biosensor based on a photonic crystal with a defective layer designed to determine the concentration of SARS-CoV-2 in water
I. M. Efimov, N. A. Vanyushkin, A. H. Gevorgyan +1
We propose a new optical biosensor based on a photonic crystal with a defect layer, which can determine the SARS-CoV-2 concentration in water by the defect mode shift. Two models o…
Scattering of a plane wave by an inhomogeneous 1D dielectric layer with gradient refractive index
N. A. Vanyushkin, A. H. Gevorgyan, S. S. Golik
We propose a new method for calculating reflection and transmission coefficients for an arbitrarily polarized electromagnetic plane wave incident on a one-dimensional dielectric me…
