Design of a bidirectional WDM module for multi-channel transceivers

摘要

A compact wavelength division multiplexing (WDM) module is designed using discrete micro optics components assembled on silicon optical bench for multiple-channel transceivers. This design is optimized for a 4-channel multiplexer (MUX) plus a 4-channel demultiplexer (DEMUX). In this design, the micro optics components for the MUX and DEMUX are integrated, and the MUX and DEMUX share the same space. This helps to minimize the number of components required and hence reduce the cost and size. Therefore, the module is compact enough to be put in small standard packages (SFF/SFP).
