A novel type of rotatable diffraction volume gratings based on cholesteric liquid crystals with
phototunable helix pitch is elaborated. For this purpose the cholesteric liquid crystalline …

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 …

Because of the presence of a selective reflection band, cholesteric liquid crystals strongly
modify the emission of fluorescent guest molecules. While emission along the helical axis is …

Strong conical lasing in the violet–blue range of the spectrum from dye doped cholesteric
liquid crystals is obtained. In contrast to the previously reported cases, the cone laser …

The out-of-normal emission in cholesteric liquid-crystal lasers is studied experimental and
theoretically. Apart from the well-known dominant laser in the direction of the helix axis …

The field-induced orientational transition in layers of cholesteric liquid crystals with spatially
periodic modulation of the surface anchoring is studied by numerical simulations and …

Novel photosensitive azobenzene-containing substances with sorbitol-and lactate-based
chiral fragments were synthesized to serve as chiral-photochromic dopants in cholesteric …

Anomalous spectral shift of transmission peaks is observed in a Fabry-Pérot cavity filled with
a chiral anisotropic medium. The effective refractive index value resides out of the interval …

This letter reports on the optimized design and operation performance of a second order
distributed feedback (DFB) dye laser based on an active organic waveguide with a volume …

Waveguide optical properties of a cholesteric liquid crystal (CLC) layer with a deformed lying
helix (DLH) have been studied by numerical simulations using the finite difference time …
