The Design and Simulation of WDM Filter Used in Two-Channel Optical Fiber Communication

With the introduction of modern optical technology, the capacity and speed of communication have been improved dramatically, and the optical fiber communication will play a more important role on the communication stage. A major difficult problem in the WDM communication system is the manufacture of the multiplexer (demultiplexer). In this article we are discussing two problems: the design of the film interference optical filter and the simulation of the coating process. The article chiefly introduces the design principle and process of a kind of WDM film interference optical filter for two channels, analyzes the performance of the filter and the effective factors. Finally the coating process is simulated.
