Method And System For Connectionless Integrated Optical Receiver and Transmitter Test

A system for communication, the system comprising:

• an optoelectronic transceiver comprising a transmit (Tx) path and a receive (Rx) path, each path comprising one or more optical switches, the optoelectronic transceiver being operable to:
• couple a first modulated optical signal to a photodetector in the Rx path via one or more optical switches when the optoelectronic transceiver is configured in a first self-test mode;
• communicate the first modulated signal to a grating coupler in the Rx path via one or more optical switches when the optoelectronic transceiver is configured in a second self-test mode;
• and
• communicate the first modulated signal to a grating coupler in the Tx path when the optoelectronics transceiver is configured in an operational mode.
