ABSTRACT:
An input light signal is guided to a light receiving element by an input optical fiber, and converted into an electric signal. This electric signal is converted again into an optical signal by a light emitting element, and this optical signal is optically and positively fed back to the light receiving element by a partially reflecting film between the light emitting element and an output optical fiber. In this way, the input optical signal can be electrically or optically converted in a two-valued state at the output side of the light receiving element or light emitting element.
