Temperature-tunable directional laser emission from a dye-doped liquid-crystal-based planar random cavity laser is presented. The optically pumped nematic liquid crystal infiltrated planar random microcavity produces an ultranarrow linewidth (0.03 nm, corresponding to Q>20,000), highly directional (1.4 ...
Liquid crystal cladding layer and two electrodes (bright patches on the left and right of the ring since they poses large surface-volume ratio, so that the surface effects and strong confinementcan be to change the anchoring of a LC on a hard substrate by controlled absorbtion of DOI: http:...
Random lasers from dye-doped nematic liquid crystal (DDNLC) cells with different rubbing methods were observed due to different random ring cavities that were formed. Through constructing cells with different rubbing methods on the forward and backward surfaces of light-emitting sides, we can get tw...
A liquid crystal display apparatus using monochromatic lasers that emit light rays of the three primary colors respectively is also proposed. In these liquid crystal display apparatuses, the three primary colors of light are mixed to generate white light. In recent years, a liquid crystal display ...

Liquid-phase epitaxy (LPE) is a solution crystal growth technique for the deposition of crystallographically oriented thin films, thick layers, or discrete crystals on a seeding or template substrate. From: Handbook of Crystal Growth: Thin Films and Epitaxy (Second Edition), 2015 ...
liquid crystal research since 1970, when F. Brochard and PG de Gennes modified the properties of liquid crystals by mixing them with submicron magnetic particles92. In recent years, with the continuous development of nanotechnology, liquid crystal light protection devices doped with nanoparticles have ...
