摘要
介绍了在光子晶体光纤(PCF)中产生超连续谱(SC)的发展现状及应用背景,从广义非线性薛定谔方程入手,讨论了超连续谱的形成机理,并从光子晶体光纤色散特性、脉冲参数等方面探讨了对超连续谱形成的影响,从而可以控制超连续谱的形成。
The development and application background of supercontinuum (SC) generation in photonic crystal fibers (PCF) are presented. From the generalized nonlinear Schrodinger equation, the formation mechanism of supercontinuum in PCFs is discussed, and the influence factors on the process of supercontinuum generation from the dispersive characteristics of PCF and parameters of input pulses are summarized. Thus the generation of supercontinuum can be controlled.
