Abstract

Optical bistable operation in the transmission characteristics of a nematic liquid crystal film is observed. The mechanism for the bistability is the self-focusing of light via optically induced molecular reorientations. The process occurs at very modest cw input laser power on the order of 0.3 W (intensity of ∼500 W/cm2) in a 60-μm-thick sample.
