Information Recording in Photosensitive Photonic Cholesteric Liquid Crystal
According to the modern conceptions the cholesteric liquid crystals (CLCs) can be considered as one dimensional 1D) photonic crystals. The existence of the selective reflection band and the ability to change the selective reflection avelength over a wide range under the action of applied external forces make it possible to use the CLCs in the data ecording, processing and storage systems. Prese...
متن کاملEnhancing cholesteric liquid crystal laser performance using a cholesteric reflector.
A high performance dye-doped cholesteric liquid crystal (CLC) laser is demonstrated by incorporating a passive CLC reflector to the active cell. The polarization-conserved CLC reflector effectively increases the distributed feedback cavity length which, in turn, results in a significant enhancement in lasing efficiency and a dramatic reduction in beam divergence. The lasing characteristics are ...
متن کاملCholesteric Liquid Crystal Flakes—a New Form
LLE Review, Volume 74 139 The last 20 years have seen a growth of mixed-media systems in which cholesteric liquid crystals (CLC’s) are one component. These include polymer-dispersed CLC’s1 in which the CLC’s are confined to microdroplets within a continuous isotropic polymer and CLC’s in gels2 in which there is a small amount of polymer to stabilize the CLC structure. In either case, the contin...
متن کاملElectrically switchable, photoaddressable cholesteric liquid crystal reflectors.
We report on the development of photoaddressable cholesteric liquid crystal (CLC) mixtures capable of large range color tuning as well as direct on-off electrical switching. The continuously photoaddressable CLC mixtures are based on a high HTP azo-containing chiral material mixed with an off-the-shelf nematic liquid crystal (QL9/E44). By polymer stabilizing the QL9/E44 mixture, it is demonstra...
متن کاملColloidal cholesteric liquid crystal in spherical confinement
The organization of nanoparticles in constrained geometries is an area of fundamental and practical importance. Spherical confinement of nanocolloids leads to new modes of packing, self-assembly, phase separation and relaxation of colloidal liquids; however, it remains an unexplored area of research for colloidal liquid crystals. Here we report the organization of cholesteric liquid crystal for...
