LIQUID CRYSTAL BASED OPTICAL SWITCHES [PDF]
Molecular Crystals and Liquid Crystals, 2004 Optical switches using two electro-optical effects in liquid crystals are proposed and investigated for incorporation in a switch matrix for optical networks. These two devices employ selective reflection in cholesteric layers and total reflection at the border between glass and nematic liquid crystal.
