一种新颖的晶体型波长分插解复用器结构设计

Design of A Novel Structure of Interleaver Based on Birefringent-Crystals

提出了一种新颖的晶体型波长分插解复用器 (Interleaver)结构 ,该结构全部采用双折射晶体来实现 ,具有 PMD补偿、PDL低和温漂小等特点 ,同时具有很小的外观尺寸。加工及装配误差分析表明这种结构的 Interleaver完全可以满足 ITU- T10 0 GHz波长间隔的解复用。

The structure of a new kind of interleaver based on birefringent-crystal is proposed, and it is realized absolutely by birefringent-crystal, which has the feature of PMD compensation, low PDL, low temperature-shift and small dimensions. The analysis of assembling tolerance shows that this kind of interleaver can meet the requirement of de-multiplexing of ITU-T 100 GHz grid.
