Abstract
An automatic shutdown system for optical multiplexers and demultiplexers includes an optical switch that is disposed in a common optical channel between a transmitter and a receiver of an optical communication system. The optical switch may attenuate or block a signal in the common optical channel during power-off conditions. The optical switch may also provide a low insertion loss and low polarization loss in the common optical channel during power-on conditions.
