中文摘要 | 光学相位共轭(OPC)技术能够同时且高效地补偿光纤传输过程中色散及非线性效应所导致的信号失真,且该技术同脉冲调制方式无关。从理论上分析了在自陡峭效应(SS)作用下高斯脉冲信号在中距相位共轭系统中的传输演化特性,数值模拟了在其作用下超短飞秒高斯脉冲的动态传输过程,讨论了自陡峭效应对中距相位共轭系统复原性能的影响。结果表明自陡峭效应将导致高斯脉冲信号发生峰值漂移和脉冲后沿变陡,相位共轭系统不能补偿由此导致的脉冲失真和畸变。引入合适的色散可以减小这种信号失真,并使得相位共轭系统能够同时补偿由于色散、自相位调制和; Optical phase conjugation (OPC) is a promising optical technology that can compensate for the distortion due to dispersion and nonlinear effects simultaneously in pulses propagating through a single-mode optical fiber. The pulse propagation characteristics influenced by self-steepening (SS) on the optical fiber system using midway OPC are analyzed theoretically. Dynamic evolution of ultra-short Gaussian pulses in the system is simulated numerically. Effects of SS on the compensation for the distortion are discussed. The results demonstrate that the SS can affect pulse propagation dynamics. The distortion due to the SS cannot be compensated by the OPC. The distortion can be counteracted by the small dispersion. |
