摘要:
A photonic integrated circuit (PIC) includes an optical transmitter and an optical receiver. An optical loopback is coupled to the optical transmitter and to the optical receiver and is configurable to provide in a communications mode a transmitted optical signal from the optical transmitter to an optical output node and to provide a received optical signal on an optical input node to the optical receiver. The optical loopback is further configurable in a loopback testing mode to optically isolate the received optical signal on the optical input node from the optical receiver and to provide the transmitted optical signal from the optical transmitter to the optical receiver. A PIC including the optical loopback enables improved optical loopback testing of optical ports that will be present on network devices including co-packaged optics.
