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.文章对二阶非线性串级效应的物理原理和基于此的全光晶体管的研究进行了综合介绍
The second-order nonlinear cascade effect, especially the phase shift obtained by the fundamental frequency light wave through the cascade process (the second harmonic generation process and the subsequent frequency down-conversion process) is a very promising way to realize the all-optical signal processing The article introduces the physical principle of the second-order nonlinear cascade effect and the research of the all-optical transistor based on this
