TL;DR: In this article, the transmission or reflection characteristics of the sensor heads depend on the environmental electromagnetic fields due to the directional change of the liquid crystal molecules, and not only the conventional nematic but also polymer dispersed liquid crystals are tested.

TL;DR: In this paper, a cascaded structure of long period fiber gratings with a liquid crystal (LC) as a surrounding medium is proposed, which is suitable for arbitrary loss filters that compensate for nonuniform optical gain in an erbium doped fiber.

TL;DR: In this article, a method of fabricating a vertically aligned liquid crystal display (LCD) using surface relief gratings is presented, where two dimensional surface gratings are produced on a photosensitive polymer by the illumination of the UV light through a photomask.

TL;DR: In this article, the stability of the optical reorientation of doped nematic liquid crystals (LCs) with azo-dyes in polymer networks has been investigated and the photo-reactive polymer networks formed within the doped LC medium play a critical role in achieving the stable optical re orientation of the LC originating from the transcis transformation of the dye molecules.

TL;DR: Elasticity-based patterning of human red blood cells into a microarray form on supported lipid membranes prepared on a solid substrate having two types of topographic patterns, porous and flat regions is described.
