利用光波在一段80 m长的微结构光纤(MSF)中的交叉相位调制效应实现了对10 GHz时钟信号的全光波长变换,变换带宽超过30 nm。该实验所使用的微结构光纤非线性系数约为11 W-1·km-1,其在1530～1570 nm波长范围内具有小的正常色散和平坦的色散曲线。实验结果表明,利用这种微结构光纤可以实现结构紧凑的宽带波长变换器。

All optical wavelength conversion of the 10-GHz clock signal is demonstrated based on cross-phase modulation of optical pulses in an 80 m long microstructure fiber (MSF), and the conversion bandwidth is over 30 nm. The experimental microstructure fiber with a nonlinear coefficient of ～11 W-1·km-1 has small normal dispersion and flat dispersion curve from 1530 nm to 1570 nm. The experimental results show that a compact wavelength converter can be realized by utilizing this microstructure fiber.
