  "textContent": "A photonics gyroscope comprises a light source on a photonics chip that emits a broadband beam; a waveguide resonator; a reflective component; first and second detectors, the second detector coupled to the source; a RIN servo loop coupled between the second detector and the source; and a rate calculation unit. The beam is directed into the resonator such that it propagates in a CCW direction. A portion of the CCW beam is coupled out of the resonator toward the reflective component and reflected back as a reflected beam that is coupled into the resonator such that the reflected beam propagates in a CW direction. The CW beam is coupled out of the resonator to the first detector, which detects a resonance frequency shift between the CW and CCW beams. The RIN servo loop stabilizes an intensity of the beam such that bias error and noise is reduced.",
