Wavelength conversion utilizing non-degenerate four-wave mixing in photonic crystal fiber

An experimental research on the wavelength conversion utilizing non-degenerate four-wave mixing in photonic crystal fiber is presented. Two pumps and a 25 m dispersion flattened and highly nonlinear photonic crystal fiber are used in our non-degenerate four-wave mixing experimental study. The wavelength conversion bandwidth is about 65 nm. The wavelength conversion efficiency is -22.7 dB when the powers of two pumps are 17.3 dBm and 13.4 dBm. The conversion efficiency in the wavelength range of 1 530 to 1 560 nm is stable.
