Liquid Light Switch Enables More Powerful Electronics

Researchers have built a miniature electro-optical switch which can change the spin -- or angular momentum -- of a liquid form of light by applying electric fields to a semiconductor device a millionth of a meter in size. Their results, reported in the journal Nature Materials, demonstrate how to bridge the gap between light and electricity, which could enable the development of ever faster and smaller electronics.

Japanese Researchers Find Cholesteric Liquid Crystals Open New Route to Planar Optical Elements

Researchers at Osaka University developed a technology to control the light wavefront reflected from a cholesteric liquid crystal - a liquid crystal phase with a helical structure. Although known for their ability to Bragg-reflect light, cholesteric liquid crystals could only be used as flat mirrors, reflecting light at the same angle as the incident angle. The new technology enables planar optical components to be made with functionality by design, contributing to the miniaturization of catoptrics devices.
