1. An integrated optical transceiver comprising:
a substrate member having a surface region;
an optical input port;
an optical output port;
a transmitter unit provided on the surface region and comprising:
a set of four laser devices configured to output four laser lights;
a set of four power splitter devices coupled to the four laser lights to split each of the four laser lights to two portions leading to two replicated transmit paths, each transmit path including,
a set of four modulator devices formed in the surface region and respectively receiving corresponding one of the two portions of the four laser lights;
a driver device coupled to the set of four modulator devices and configured to drive each modulator device to modulate a respective one of the four laser lights;
a multiplexer device configured to couple the four laser lights and multiplex to one output light carrying the four wavelengths delivered to the optical output port;
a receiver unit provided on the surface region with two replicated receive paths, each receive path comprising:
a demultiplexer device configured to receive an input light from the optical input port and demultiplex to four input optical signals;
a photodetector device configured to receive the four input optical signals and convert the four input optical signals to respective electrical signals; and
a transimpedance amplifier device coupled to the photodetector device to process the electrical signals to be transferred as electrical outputs; and
a heterogeneous integration configured using the substrate member, the transmitter unit, and the receiver unit to form a single silicon photonics device.
