Abstract: An optical cavity is formed to have a circuitous configuration. The optical cavity is configured to receive light coupled from a waveguide. At least two photodetector sections are formed over respective portions of the optical cavity. Each of the at least two photodetector sections is configured to detect light present within the optical cavity. Each of the at least two photodetector sections is configured for separate and independent control.
