Monolithically integrated system on chip for silicon photonics

A method of performing self-test to a monolithically integrated system-on-chip device configured for a multi-rate and selected format of data communication, method comprising:

• using the device comprising:
• a substrate member made by silicon;
• a data input/output interface provided on the substrate member and configured for a predefined data rate and protocol;
• an input/output block provided on the substrate member and coupled to the data input/output interface, the input/output block comprising a SerDes block, a CDR block, a compensation block, and an equalizer block, the SerDes block being configured to convert a first data stream of N into a second data stream of M, each of the first data stream having a first predefined data rate at a first clock rate and each of the second data stream having a second predefined data rate at a second clock rate;
• a silicon photonics device formed on the substrate member having at least an optical multiplexer;
• a pair of laser devices coupled to the silicon photonics device;
• a switch configured to select one of the pair of laser devices to be coupled to the optical multiplexer to provide for a redundant laser device outputting a laser signal;
• a signal processing block provided on the substrate member and coupled to the input/output block, the signal processing block configured to the input/output block;
• a driver module provided on the substrate member and coupled to the signal processing block, the driver module being configured to modulate the laser signal;
• a driver interface provided on the substrate member and coupled to the driver module and the silicon photonics device, the driver interface being configured to transmit output data in either an amplitude modulation format or a combination of phase/amplitude modulation format or a phase modulation format via modulated laser signal;
• a receiver module comprising a TIA block provided on the substrate member and to be coupled to the silicon photonics device, and configured to the signal processing block to communicate information to the input/output block for transmission through the data input/output interface;
• a communication block provided on the substrate member and operably coupled to the input/output block, the signal processing block, the driver block, and the receiver block;
• a communication interface coupled to the communication block;
• and
• a control block provided on the substrate member and coupled to the communication block;
• initiating a signal from the control block to initiate a laser bias or a modulator bias;
• and
• tuning, using the control block, the silicon photonics device.
