Method of Chirp Elimination for DFB Laser Using a Linearly Chirped Fiber Grating

对线性啁啾光纤光栅消啁啾技术进行了理论和数值分析 ,给出光纤光栅设计中的一些重要参数 ,并与F -P光谱窗消啁啾法和正常色散光纤消啁啾法做了比较。研究结果表明 ,光纤光栅的啁啾消除效果要好于其他两种方法 ,尤其是在消除非线性啁啾方面效果更为突出。

The use of a linearly chirped fiber grating for chirp elimination is numerically and theoretically discussed.Some important parameters are given for designing the optical fiber gratings.The results show that the effect of chirp elimination using a linearly chirped fiber grating is better than that using normal dispersion optical fibers or F-P cavity,especially in canceling nonlinear chirp.
