可重构光分插复用器的设计与实现

研究了基于光纤光栅光开关的可重构光分插复用器（ROADM）的设计和实现.提出了一种光纤光栅准直器的结构,由光纤光栅准直器组成的光纤光栅光开关真正实现了光纤光栅与光开关合二为一的结构.以光纤光栅光开关为核心模块,制作了一种ROADM,该器件结构更紧凑,体积更小.通过对样机的测试和系统仿真,结果证明了此种结构的ROADM符合设计标准,具有较高的性能,而且结构简单,操作方便.此外,该ROADM制作过程难度小,器件成本低,适合批量生产.

Design and Implementation of ROADM

The design and implementation of ROADM based on the FBG optical switch (OSW) was investigated. A new fiber Bragg grating (FBG) collimator was designed, and the construction of which is introduced. The FBG optical switch (OSW), composed of FBG collimators, was the integrated package of FBG and OSW. A new ROADM, which is compacter and smaller, was designed based on FBG OSW. Having tested the ROADM and simulated the system according to the performance standards of ideal OADM, a conclusion can be drawn that the newly designed ROADM is simple in structure and easy to be operated. In addition, this new ROADM, applied with mature technology, can minimize the facture difficulties and reduce the cost.
