摘要 利用光子晶体光纤(PCF)在10 Gb/s光传输系统中对普通单模光纤中传输的光脉冲进行了色散补偿,获得了很好的补偿效果。实验中,10 Gb/s光脉冲序列经过2.163 km普通单模光纤被展宽后,利用26 m长光子晶体光纤对其进行色散补偿,补偿后脉冲基本恢复到了初始形状。进一步的理论计算表明,此光纤在C波段20 nm波长范围内对普通单模光纤能够实现较好的色散斜率补偿,补偿后剩余色散小于5 ps/nm。理论与实验结果表明光子晶体光纤在色散补偿方面具有很大的潜力,在未来光通信系统中将发挥重要作用。 The experiment on dispersion compensation of 10 Gb/s pulses using photonic crystal fiber (PCF) is reported. In experiment, 26 meter-long PCF is used to compensate the dispersion of 2. 163 km G. 652 fiber. Experiment results show that the broadened pulses have recovered initial shapes after propagating through the PCF, so the effect of dispersion compensation is favorable. Additionally, the theoretical calculation shows that the PCF can be used for slope dispersion compensation in about 20 nm bandwidth of C band and the residual dispersion is less than 5 psnm. PCF will play an important role in optical fiber communication, especially in dispersion compensation.
