The Effect of Defect Layer on Lasing in Cholesteric Liquid Crystal
A. H. Gevorgyan, K. B. Oganesyan, N. Sh. Izmailian +9
The photonic density of states (PDS) of eigen polarizations (EPs) in cholesteric liquid crystal (CLC) cells with a defect layer inside are calculated. The dependences for the PDS a…
The Influence of Absorption and Gain on Photonic Density of States
A. H. Gevorgyan, K. B. Oganesyan, N. Sh. Izmailian +8
The photonic density of states (PDS) of the eigen polarizations (EPs) in cholesteric liquid crystal (CLC) cells are calculated. The exact analytic expressions for the reflection an…
Polarization Properties of the Cholesteric Liquid Crystals
A. H. Gevorgyan, M. Z. Harutyunyan, K. B. Oganesyan +5
In the present paper, we investigate the polarization properties of the cholesteric liquid crystals (CLCs) with an isotropic/anisotropic defect inside them. Possibilities of amplif…
Radiation Peculiarities in Chiral Photonic Crystals
A. H. Gevorgyan, K. B. Oganesyan, E. A. Ayryan +2
The peculiarities of defect modes and reflection spectra of chiral photonic crystals (CPC) with an isotropic defect for various thicknesses of the defect layer was investigated. Th…
Physics of Chiral Photonic Crystals with Defect
Ashot H. Gevorgyan, Koryun B. Oganesyan, Edik A. Ayryan +3
Specific features of the defect modes of cholesteric liquid crystals (CLCs) with an isotropic defect, as well as their photonic density of states, Q factor, and emission, have been…
Cholesteric liquid crystals with tunable defect inside
A. H. Gevorgyan, K. B. Oganesyan, E. A. Ayryan +2
Peculiarities of the defect modes of cholesteric liquid crystals (CLCs) with an isotropic/anisotropic defect inside are investigated. The influence of the defect layer thickness an…
