ABSTRACT:
Magnetooptical switches for application in optical communication and data processing systems for switching, multiplexing, and demultiplexing take improved compact forms for switching unpolarized optical signals from one multimode fiber guide to selected ones of a plurality of such fiber guides. Reflection and transmission switches are provided, as well as devices for simultaneous switching of both upstream and downstream light waves.
