  • Integrated inter-cavity photodetector for laser power and threshold estimation
    Patent number: 11075503
    Abstract: A multi-section laser device is configured with a gain section and an integrated photodetector section. The photodetector section, rather than being a separate component, is integrated directly into the body of the laser. The integrated photodetector section absorbs photons generated by the gain section and creates a photocurrent that is proportional to the output of the multi-section laser device. The measured photocurrent is usable to calculate power output of the multi-section laser device and to identify any adjustments that may be needed to be made to the laser in order to achieve desired laser light output.
