Abstract
Abstract A nonlinear optical element for use in a light-light switching element or optical memory element of an optical information system which is controlled by a control light. The nonlinear optical element comprises an optical active layer having dielectric samples or semiconductor samples which cause a nonlinear optical effect, wherein their shapes and sizes are selected so that the electric field of exciton resonance energy in the sample increases in resonance with size of the sample.
