摘要： 分析了一种可调节的偏振模色散(PMD)补偿器,该补偿器是一个高双折射光纤制成的非线性啁啾光纤光栅,并首次分析了该非线性啁啾光纤光栅中的光谱特性和时延曲线;同时采用一个压电转换(PZT)拉伸器对该光栅进行均匀拉伸,以达到调节的目的.最后提出了一种PMD自适应补偿方案.

Abstract: We make a study of a tuning high birefringence nonlinearly chirped fiber Bragg gratings (Hi-Bi-NLCFBG) used to compensate the polarization mode dispersion (PMD) of the high-speed optical fiber communication system and analyze the spectrum characteristics and time-delay for the first time. A method for tuning the Hi Bi NLCFBG by means of PZT is suggested. Finally, we advance a scheme to compensate PMD by a self-adaptive method.

Key words: piezoelectric transition (PZT), self-adaptive compensation, polarization mode dispersion (PMD), high-birefringence nonlinearly chirped fiber Bragg gratings (Hi-Bi-LNCFBG), quadratic chirp
