建立了具有两个取样周期略有不同的取样光纤光栅反射镜的Vernier波长调谐机制的光纤分布布拉格反射式激光器的数值仿真模型,对激光器的输出特性进行了分析.研究了激光器输出特性随着激光器前后光栅反射镜波长以及前后光栅反射镜反射率的变化关系.提出了对两取样光栅反射率的优化配置方案,可以使输出激光的边模抑制比有所提高;同时对波长调节方式也进行了探讨;进行了实验研究.
A numerical simulation model of fiber distributed Bragg reflection laser with Vernier wavelength tuning mechanism with two sampling periods with slightly different sampling fiber grating mirrors is established and the output characteristics of the laser are analyzed.It is studied that the output characteristics of the laser vary with the laser The front and back grating mirror wavelength and the front and rear grating mirror reflectivity changes. The proposed two-sample grating reflectivity optimization scheme can be output laser edge mode suppression ratio has improved; the same time, the wavelength adjustment mode Explore; experimental study.
