Control systems for optical devices and subassemblies

An optical module or subassembly for communication with a host board, the optical module or subassembly comprising:

• a transmitter optical subassembly for receiving an electrical signal and converting the received electrical signal into an optical signal;
• a transmitter drive coupled to the transmitter optical subassembly;
• a receiver optical subassembly for receiving an optical signal and converting the received optical signal into an electrical signal;
• a receiver interface coupled to the receiver optical subassembly;
• and
• a control system in electrical communication with the host board,
• wherein the control system comprises:
• a programmable central processing device including a field programmable gate array (FPGA);
• monitoring and processing circuitry including application specific integrated circuit (ASIC), wherein the monitoring and processing circuitry is coupled to the programmable central processing device and is programmable for implementation into an optical device physical and transport layer communications specifications for a plurality of different applications, and includes analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC) functions, and wherein the monitoring and processing circuitry is configured to be in communication with photonic integrated circuits including a thermoelectric cooler (TEC), a transmitter photonic integrated circuit (Tx-PIC), a receiver photonic integrated circuit (Rx-PIC), and a wavelength locker;
• a high bit rate data and clock interface coupled to the FPGA and configured to send and receive data between a host controller and the FPGA;
• and
• a control interface coupled to the FPGA and configured to send and receive monitoring and control data to the host board.
