分析了影响基于光纤光栅和马赫曾德尔干涉仪的光分 插复用器 (OADM)的特性的原因 ,根据理论分析和模拟计算 ,提出通过监控输入端口的背向反射光特性和局部加热的方法来判断和相应调整器件的参数 ,并用来模拟紫外激光修正过程。实验结果验证了这一方法的可行性。
The reasons that affect the characteristics of optical add / drop multiplexer (OADM) based on fiber grating and Mach-Zehnder interferometer are analyzed. According to theoretical analysis and simulation calculation, a method of monitoring the characteristics of back-reflected light and local heating of input port is proposed To determine and adjust the parameters of the device, and used to simulate the UV laser correction process. The experimental results verify the feasibility of this method.
