LIQUID CRYSTAL COMPOSITE, CELL, DEVICE, AND METHOD THEREOF

The invention provides a liquid crystal (LC) composite, a LC cell, a LC device, and a method thereof. The LC composite comprises (i) a liquid crystal material, and (ii) a copolymer polymerized from LC monomers and non-LC-monomers; and the LC composite is mechanically stressed/sheared. The invention exhibits numerous merits such as high transmittance in visible and IR range, hysteresis free, and a simple fabrication process; and may be utilized in LC device applications such as adaptive optics e.g. beam steering devices and fast tip-tilt wavefront correctors; and general optical applications such as eye wears, compact cameras and compact telescopes.
