Optoelectronic add/drop multiplexer

摘要

An optoelectronic add/drop multiplexer is disclosed having an optically transmissive block optically coupled to an incoming WDM signal having a two or more incoming optical signals. The add/drop multiplexer further includes one or more drop bandpass filters adapted to remove one or more incoming optical signals from a multi-channel signal flow in a first direction within the optically transmissive block and one or more add bandpass filters adapted to add one or more output optical signals to the multi-channel signal flow in a second direction within the optically transmissive block.
