Nonlinear active light waveguide material composed of a dopant having multiple donor--acceptor systems

摘要

The present invention relates to a nonlinear active light waveguide material consisting of a dopant with a multiple donor--acceptor system and comprising an optically transparent polymer and an optically nonlinear active optical waveguide composed of a nonlinear optical dopant composed of one or more donor-Dopant consisting of one or more donor--acceptor units. Specifically, a dopant in which donor--acceptor units are arranged in a cyclic group has a high hyperpolarity and a donor-Particularly suitable doping agents for use with a charge transport absorption band wavelength approximately equal to that of a dopant with a scepter unit are the calix (4) areen, which are provided with an acceptor group in the upper ring and a donor group in the lower ring And have superior depolarizability, the compounds are readily soluble in host polymers such as PMMA and polystyrene, and have low wavelength Since the charge transfer absorption band of the document, and optionally a non-linear active optical waveguide structures containing such dopants it is also characterized in that suitable for use as a frequency doubler.
