摘要： A WDM add/drop module. The drop portion of the add/drop module is accomplished by using thin film filters or thin film interleavers. The add portion of the add/drop module uses fused fiber interleavers for the less critical stages of the multiplexing process. In a final stage, fused fiber interleavers can be placed in series. A thin film intervleaver having a flattop frequency response may also be used for the critical stage where the multiplexed channels are more closely spaced. The frequency response of the thin film interleaver is relatively constant across a bandwith of a channel while having a drop off at the channel edge to reduce cross talk.

摘要： Disclosed is an add-drop multiplexer that receives an optical signal having a plurality of channels. The multiplexer spatially separates the channels, and a spatial light modulator within the multiplexer, which in some embodiments is a switched blazed grating, routes the channels along first or second paths according to whether the particular channels are to be sent along as a part of an output communication signal or “dropped” into a dropped-channel optical communications signal. The add-drop multiplexer is also operable to receive optical channels to be added to an optical signal and to use a spatial light modulator to add those optical signals to that optical signal.
