Photonics stabilization circuitry

A device, comprising:

• an opto-electrical detector configured to output an electrical signal based on a measurement of light intensity of a photonics-based component, the light intensity being proportional to an amount of detuning of the photonics-based component;
• analog-to-digital conversion (ADC) circuitry configured to output a digital signal based on the electrical signal output from the opto-electrical detector, wherein the ADC circuitry comprises a dual-slope integrating ADC;
• feedback control circuitry configured to tune the photonics-based component based, at least in part, on the digital signal output from the ADC circuitry;
• and
• a digital controller configured to:
• receive the digital signal output from the ADC circuitry;
• generate a digital pulse sequence based, at least in part, on the received digital signal;
• and
• provide the digital pulse sequence to the feedback control circuitry.
