The sensitivity of refractive index sensors based on defected 1D photonic crystals: an analytical approach
Nikolay A. Vanyushkin, I. M. Efimov, Ashot H. Gevorgyan
In this paper, an analytical formula for the sensitivity of optical sensors based on one-dimensional photonic crystals (PCs) with a defect was derived for the first time. Based on…
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…
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…
