首先介绍了DWDM系统中窄带F-P薄膜滤光片的历史背景和研究现状以及发展前景。作为背景知识，介绍了光的传输矩阵，光的偏振状态，干涉滤光片，F-P腔的工作原理，DWDM系统对薄膜干涉滤光片的基本要求，为了满足设计要求一方需要精心选择基板和薄膜材料，另外一方面要寻性能优良的膜系。接下来，先给出了几种常见的膜系结构，然后通过MATLAB仿真得出其透射曲线。通过其透射曲线分析得出设计滤光片的的几条结论。最后给出了两种设计满足设计要求的滤光片的寻优方法：对称周期膜法和主体参数寻优法。 关键词：密集波分复用、F-P滤波器阻火带、薄膜干涉滤波器、膜系设计
Abstract
With the development of DWDM technology, filter as an important element of DWDM system also get a rapid development. In this page the design of narrow band F-P film optic filter used in DWDM system will be described.
First, the history, research actuality and research foreground of narrow band F-P film interference filter used in DWDM system are described. Second the matrix of optic transmit, the polarization state, interference optic filter, the F-P filter are present. The basic performance of film interference filters used in DWDM system are presented. In response to the requirement it is important that coating materials and substrates must be selected carefully. In this passage we give different film, adopting the method of simulated on the MATLAB. At last, there are two better design methods: symmetry cycle film method and principal part excellent method.
Key words:电子优惠券 DWDM, F-P filter, film interference filter, film design
