ABSTRACT:
An optical communication system is implemented using a Sagnac switch to generate a new data signal from a received deteriorated data signal using a clock signal which operates in frequency synchronism but not in phase synchronism with the received data signal. In another embodiment, an optical communication system is implemented by stretching out the loop of the Sagnac switch so that the system transmitter includes the control signal coupler of the Sagnac switch, the receiver includes the combining coupler of the Sagnac switch and the loop becomes the optical communication path connecting the transmitter and receiver.
