摘要
二阶非线性串级效应,特别是基频光波通过串级过程(二次谐波产生过程和随后的频率下转换过程)获得的相移,是实现全光信号处理的一条非常有希望的途径.
Cascaded second-order non-linear optical effects,specifically the phase-shift that a fundamental frequency wave experiences through cascading during second-harmonic generation and the successive down-conversion,are a promising route to all-optical signal processing.The physical principle of cascaded second-order nonlinear optical effects and their applications in all-optical transistor action are reviewed.
