摘要

改变啁啾光栅轴向温度场的梯度

可使得该非周期光栅轴向上不同位置的反射波长发生相应的变化

从而改变光栅的啁啾量

达到调节色散的目的。文章通过在可调色散补偿器中封装两个分别具有正、负色散的光纤布拉格光栅（FBG）

实现了色散调节范围达到-900

00 ps/nm的可调色散补偿（TODC）技术。这种方式具有无机械调节运动装置和可靠性高的优点。

Abstract

When the chirped grating axial temperature gradient is changed

its reflection wavelengths in different positions in the non-periodic grating axis will change accordingly

thus altering the chirp of the grating and achieving the purpose of regulating the dispersion.In this paper

a Fiber Bragg Grating（FBG）-based Tunable Optical Dispersion Compensator（TODC） with positive and negative dispersions is designed and implemented with its adjustment range up to-900

00 ps/nm.This design is characteristic of no mechanical adjustment device

long working life and high reliability.
