摘要
基于均匀布拉格光纤光栅的色散特性,阐述丁激光啁啾脉冲的传输演变特性,研究了工作于传输方式的非啁啾光纤光栅的透射传输特性。讨论了光源线宽、光栅长度、光栅耦合系数等光栅参数以及初始脉宽、初始啁啾等参量对补偿光纤长度的影响,通过理论计算和模拟实验研究光栅对脉冲的补偿能力。
Based on the dispersion characteristics of united Bragg fiber grating, the transmission performance of laser pulse in G.652 optic fiber and the non-chirped grating was demonstrated. The effect to the compensated optic fiber length of laser linewidth, grating length, coupling coefficient of the grating compensators, and the pulse initial width , chirped parameter was discussed. By theoretic account and simulated experiment, the compression ability of the united Bragg fiber grating to pulse was analyzed.
