Cholesteric liquid crystals (CLCs) have a photonic bandgap due to the periodic change of
refractive index along their helical axes. The CLCs containing optical gain have served as …

Using the exact analytical expressions for the reflection and transmission matrices for the
finite thickness cholesteric liquid crystal (CLC) layer, we calculated its photonic density of …

Flexible photonics has the potential to develop artificial skins with superior sensing
capabilities. As an essential skin function, the tactile simulation is, however, still challenging …

We investigated peculiarities of absorption, emission and photonic density of states of a
cholesteric liquid crystal with an isotropic defect layer inside. The influence of the defect …

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 and light …

The generation of the diffusion radiation by the charged particle passing through the random
stack of plates is considered in the IR region. The diffusion radiation originates due to the …

We have analyzed peculiarities in the localization of light in a layer of a cholesteric liquid
crystal (CLC) for the normal incidence of light. It is shown that dielectric boundaries strongly …

Peculiarities of the defect modes of cholesteric liquid crystals (CLCs) with an
isotropic/anisotropic defect inside are investigated. The influence of the defect layer …

The features of the optical properties of cholesteric liquid crystals (CLC) with enormous
magneto-optical activity were investigated. It is shown that the system under consideration …

Complex optical investigations were performed in one-dimensional (cholesteric) and three-
dimensional (Blue Phase II) liquid-crystalline photonic crystals. Spectra of optical …
