Analysis of defect modes in one-dimensional photonic crystals with two defects
A. O. Kamenev, N. A. Vanyushkin, I. M. Efimov +1
In this paper, for the first time, analytical expressions for determination of the wavelength of defect modes (DMs) in one-dimensional (1D) photonic crystals (PCs) with two defect…
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…
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…
