All-Optical Wavelength Conversion Based on Photonic Crystal Fiber
基于光子晶体光纤的全光波长变换研究

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.
