温度对FBG外腔半导体激光器模式的影响
Influence of temperature on FBG-ECL mode
摘要
文章基于四阶龙格—库塔法,引入光纤光栅的位相分布,并考虑光线在外腔中的往返相移,分析了温度和外腔长度对布拉格光纤光栅外腔半导体激光器(FBG-ECL)模式的影响。数值模拟的结果表明:随着温度的升高和外腔长度的增加,FBG-ECL模式数增多,模式间距变小;外腔长度的变化对FBG-ECL模式跳变的影响明显。
Abstract
Introducing the phase distribution of fiber grating and taking into consideration the back-and-forth phase shift of the light in the external cavity, this paper analyzes the influence of temperature and the length of the external cavity on the Fiber Bragg Grating (FBG)-External Cavity semiconductor Lasers (ECL) mode by using four-order Runge-Kutta method. The numerical simulation results show that the number of the FBG-ECL mode increases and the intermode spacing decreases with the increase of temperature and external cavity length and the influence of the changes of the external cavity length on the hopping of the FBG-ECL mode becomes obvious.
