光波导中二次谐波的非线性光学现象及其应用

Nonlinear Optical Phenomena and Application of SHG in Optical Wave Guide

本文以平板光波导为主,讨论了三层和四层结构平均光波导的非线性二次谐波效应。以基波和二次谐波相互作用出发,作了必要的理论分析,并给出了实验结果。此外,对于其它应用也作了讨论和展望。

In the paper, nonlinear optical phenomena of SHG in opticalwave guide on having three and four thin films are thorough discussed. The paper analyses in theory according the effects between basic and SHGwaves, and gives experimental results. The paper discusses and looks intothe future of their application.
