DISTRIBUTED SPATIAL MODE PROCESSING FOR SPATIAL-MODE MULTIPLEXED COMMUNICATION SYSTEMS

摘要

A method and system for distributed spatial mode processing is disclosed where a plurality of optical signals is received via a plurality of spatial modes on a first optical link, spatial mode conversion is performed on the plurality of optical signals to switch the plurality of optical signals to different ones of the plurality of spatial modes and the plurality of optical signals is transmitted via the different ones of the plurality of spatial modes on a second optical link where spatial mode filtering may occur.

1. A method, comprising:
receiving a plurality of optical signals over an optical link, each optical signal received via a respective one of a plurality of spatial modes of the optical link, the optical link including a particular spatial mode not used for the receiving; switching each optical signal received from its respective one of the plurality of spatial modes to a respective different one of the plurality of spatial modes via the particular spatial mode; transmitting each optical signal via its respective different one of the plurality of spatial modes; and filtering the particular spatial mode to reduce a crosstalk signal on the particular spatial mode resulting from the switching.
