一种基于布喇格光栅的可调色散补偿技术

摘要

色散补偿型光栅是非周期光栅,采用改变光栅轴向温度场梯度,可使得光栅轴向上不同位置的反射波长发生不同的变化,从而改变啁啾量,达到调节色散的目的.基于这一理论设计了一种基于光纤布喇格光栅的可调色散补偿器,具有无机械调节运动装置,模块可靠性高,色散的调节范围可达到为800ps/nm.%The optical dispersion compensator fiber grating is non-cyclical fiber grating ,that is chirp fiber grating .If the Grating axial temperature gradient was changed, the axial grating reflection wavelength at different positions would be changed to achieve the purpose of regulating the dispersion. The tunable dispersion compensator based on fiber Bragg grating (FBG) was Designed and implemented in this paper. There is no mechanical adjustment device in this approach, it is a long working life, high reliability.
