We report on the performance of an integrated four-channel parallel optical transceiver built in a CMOS photonics process, operating at 28 Gb/s per channel. The optical engine of the transceiver comprises a single silicon die and a hybrid integrated DFB laser. The silicon die contains the all functionalities needed for an optical transceiver: transmitter and receiver optics, electrical driver, receiver and control circuits. We also describe the CMOS photonics platform used to build such transceiver device, which consists of: an optically enabled CMOS process, a photonic device library, and a design infrastructure that is modeled after standard circuit design tools. We discuss how this platform can scale to higher speeds and channel counts.
