制备非中心对称的NMOB/CdA交替Y型累积LB膜,测量了它的二阶非线性光学特性.为了改善多层膜的有序性,研究在拉制NMOB/CdA多层膜时提高膜均匀性的两种方法,增强了它的二阶非线性光学特性.最后,制备光栅耦合的NMOB/CdA多层膜光波导测量了它的Cerenkov相位匹配光学二次谐波产生.
The non-symmetric NMOB / CdA alternate Y-type cumulative LB films were prepared and their second-order nonlinear optical properties were measured. In order to improve the orderliness of multilayer films, The two methods enhance their second-order nonlinear optical properties.Finally, grating-coupled NMOB / CdA multilayer optical waveguides were fabricated to measure the Cerenkov phase-matched optical second harmonic generation.
