  • Photonics stabilization circuitry
    Patent number: 11686902
    Abstract: Methods and apparatus for tuning a photonics-based component. An opto-electrical detector is configured to output an electrical signal based on a measurement of light intensity of the photonics-based component, the light intensity being proportional to an amount of detuning of the photonics-based component. Analog-to-digital conversion (ADC) circuitry is configured to output a digital signal based on the electrical signal output from the opto-electrical detector. Feedback control circuitry is configured to tune the photonics-based component based, at least in part, on the digital signal output from the ADC circuitry.
    Type: Grant
    Filed: June 17, 2022
    Date of Patent: June 27, 2023
    Assignee: Lightmatter, Inc.
    Inventors: Carlos Dorta-Quinones, Carl Ramey, Omer Ozgur Yildirim, Chithira Ravi, Shashank Gupta, Nicholas C. Harris
