摘　　要：选用具有高非线性系数和非常灵活色散特性的光子晶体光纤(PCF)作为波长变换的媒质,对基于光子晶体光纤四波混频效应的波长变换进行了理论分析,设计实验系统,并进行了实验.实现了中心波长在1550nm附近、基于PCF四波混频效应的全光波长变换,最大转换效率-22dB,转换带宽28nm.The theory of four-wave-mixing-based wavelength conversion was analyzed. Base on the theory,a wavelength conversion system was designed,in which Photonic Crystal Fiber （PCF） was used for its high nonlinearity and very flexible dispersion. Then the wavelength conversion based on four-wave mixing （FWM） was demonstrated experimentally in a 40-m-long dispersion-flattened highly nonlinear PCF. A conversion efficiency of about -22 dB and a bandwidth of about 28 nm were measured. The experimental result agrees well with the theoretical analysis.
