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 the size of the sample.
