摘要
分析了谱共轭技术用于补偿光纤色散和非线性的基本原理。通过对超高斯脉冲的数值计算表明,谱共轭技术(SPC)较时域相位共轭技术(TPC)能更好地恢复波形失真。为了弥补SPC不能补偿脉冲内拉曼散射的缺点,提出将SPC和TPC结合使用的方法。将其作用于光孤子串脉冲,不仅进一步优化了整形效果,而且还能有效抑制孤子自频移。
The basic theory of compensation of waveform distortion due to dispersion and nonlinear effect is introduced by using spectral phase conjugation （SPC）. The supper-Gaussian is calculated. The results show that SPC is better than temporal phase conjugation （TPC） in pulse distortion. Because the intrapulse Raman scattering is not compoensated by SPC, a hybrid scheme combining SPC and TPC is presented. The superior performance is obtained and the Ramn-induced frequency shift is restrained.
