摘要

文章提出一种基于磁场变化对均匀周期光纤光栅（FBG）引入线性啁啾的特性来实现可调整偏振模色散（PMD）补偿的技术。这种全光型PMD补偿技术在实现调整的同时能保持中心波长固定不变

而且能够灵活方便地实现不同的微分群时延量（DGD）。针对10Gbit/s非归零（NRZ）传输系统

采用这种技术对进行PMD补偿的模拟计算结果表明

接收信号的眼图在补偿后得到了显著改善。

Abstract

A novel technique of tunable polarization mode dispersion （PMD） compensation based on fiber Bragg grating （FBG） is proposed. In this method

tunable linear chirp is introduced to a uniform fiber grating by magnetic field

while the central wavelength does not change. This all-fiber PMD compensation technique is cost-effective and flexible in achieving differential group delay （DGD）. The result of numerical simulation on a 10 Gbit/s NRZ transmission system demonstrates a significant improvement in the eye pattern by employing the PMD compensator.
