用于光WDM网中的高反射损耗可调F-P腔的设计

Design of a Tunable FP Cavity Used in Optical WDM Networkwith High Reflection Loss

设计了具有高反射损耗特性的光解复用器，它具有插入损耗小，反射损耗大，并且可以进行电压调谐的特点。

In the WDM optical network, a tunable FP cavity is often used as a demultiplexer. But the traditional structure has the shortcoming that the reflective light is too strong and this will bring trouble to the transmmiter and EDFA in the network system. To solve this problem, isolators are often used. But this will cause an extraloss. Besides, it will costs too much. A new type of tunable FP cavity is designed in this paper. Its insert loss is low and there is almost no reflective light from the FP cavity. Finally, it can be tuned electronically.
