Abstract
Designed is a new type of photonic crystal fiber (PCF) with high nonlinearity and low loss, and it gives high nonlinear coefficient of 35.78W-1·km-1 and low loss of 2.5db/km at the wavelength of 1.55μm. Then, a wavelength conversion system based on the crossphase modulation (XPM) of the high nonlinear photonic crystal fiber is proposed. Experimental results show that when the wavelength and power of the pump light are 1565nm and 0dBm respectively, the wavelength and power of the signal light are 1545nm and 10dBm respectively, and the wavelength and bandwidth of the filter are 1565.2nm and 0.1nm respectively, the system can obtain the best wavelength conversion effect.
