Abstract:
Methods and systems for an optoelectronic built-in self-test (BIST) system for silicon photonics optical transceivers are disclosed and may include, in an optoelectronic transceiver having a transmit (Tx) path and a receive (Rx) path, where the Rx path includes a main Rx path and a BIST loopback path: generating a pseudo-random bit sequence (PRBS) signal, generating an optical signal in the Tx path by applying the PRBS signal to a modulator, communicating the optical signal to the BIST loopback path and converting to an electrical signal utilizing a photodetector, the photodetector being a replica of a photodetector in the main Rx path, and assessing the performance of the Tx and Rx paths by extracting a PRBS signal from the electrical signal. The transceiver may be a single complementary-metal oxide semiconductor (CMOS) die or in two CMOS die, where a first comprises electronic devices and a second comprises optical devices.

Claim (Index 22):
A method for communication, the method comprising:\n in an optoelectronic transceiver on an optoelectronics die and one or more electronics die, the transceiver having a transmit (Tx) path and a receive (Rx) path, the Rx path comprising a main Rx path and a built-in self-test loopback path: generating a first electrical signal in the Tx path in the electronics die; generating a pseudo-random bit sequence (PRBS) signal in the electronics die; multiplexing the first electrical signal with the PRBS signal in the electronics die; generating a first optical signal in the Tx path by applying the multiplexed electrical and PRBS signals to an optical modulator in the optoelectronics die; receiving a second optical signal in the Rx path and converting to a second electrical signal utilizing a photodetector in the main Rx path; communicating the first optical signal to a portion of the built-in self-test loopback path in the optoelectronics die; converting the first optical signal to a third electrical signal in the Rx path utilizing a loopback photodetector in the built-in self-test loopback path, the loopback photodetector being a replica of a photodetector in the main Rx path; multiplexing the second and third electrical signals in the Rx path in the electronics die; extracting, in the electronics die, the PRBS signal and the first electrical signal from the multiplexed second and third electrical signals; and assessing performance of the Tx and Rx paths by reducing an input power of the optical signal in the Tx path while monitoring a bit error rate.
