摘要
根据光脉冲在双折射色散阶跃光纤中调制不稳定性,研究了双折射色散阶跃光纤中调制不稳定性增益谱随传输距离的变化关系。结果表明:在弱双折射色散阶跃光纤和强双折射色散阶跃光纤中,利用调制不稳定性增益谱随传输距离的变化关系可分离和提取THz脉冲。
Based on the modulation instability of light pulse in the birefringence step-wise decreasing fiber, modulation instability gain as a function of propagation distance are studied. The results show that THz pulse can be separated and obtained by use of relation between modulation instability gain and propagation distance in strong birefringence fibers and in weak birefringence fibers.
