Abstract
An optical transceiver includes a silicon photonics substrate, transmitter circuitry, and receiver circuitry that are heterogeneously integrated. The transmitter circuitry includes a plurality of laser devices formed on the silicon photonics substrate, each of the plurality of laser devices configured to generate a respective laser light, a plurality of modulators formed on the silicon photonics substrate, each of the plurality of modulators configured to modulate the laser lights based on driver signals and output, from the silicon photonics substrate, the modulated laser lights, and a driver formed on the silicon photonics substrate and configured to generate the driver signals. The receiver circuitry includes a photodetector configured to receive a plurality of optical signals and convert the plurality of optical signals to respective electrical signals and a transimpedance amplifier device configured to receive the electrical signals and output the electrical signals from the silicon photonics substrate as electrical outputs.
