organic materials with nonlinear optical properties and device having non-linear optical properties.

摘要

Organic nonlinear optical materials and nonlinear optical devices are provided. The organic nonlinear optical materials are either derivatives of p-(N,N-dialkyl)amino- beta -nitrostyrene represented by the structural formula (1) or derivatives of p-( beta -nitroethylenyl)-julolidine represented by the structural formula (2). CHEM The organic nonlinear optical materials may be contained in optical cells or like containers to be used in optical devices, an alternatively they may be dispersed in various polymer materials or copolymerized with other monomer materials to form transparent dispersions or copolymers which can be used for similar purpose. The thus prepared optical media (1) may be assembled in optical devices in which the nonlinear optical properties, e.g. nonlinear refractive indice of the materials are used to fabricate optical switches, optical memories or other optical devices.
