Control of laser frequency in an optical gyroscope with a ring resonator

A photonic device comprising:

• a laser configured to generate light;
• a weak value device comprising a ring resonator, the weak value device configured to receive light from the laser and modify said light to form return light;
• and
• a stabilizing structure configured to generate a tuning signal based on the return light and control one or more of the laser or the ring resonator using the tuning signal to lock a frequency of the laser to a resonance frequency of the ring resonator.

An optical gyroscope system, comprising:

• a laser source;
• a weak value device optically coupled to the laser source, the weak value device comprising a ring resonator configured to interact with light from the laser source to produce a stabilization light component and a rotation-sensing light component;
• a stabilization circuit configured to receive the stabilization light component and generate a tuning signal therefrom to lock a frequency of the laser source to a resonance frequency of the ring resonator;
• and
• a detector configured to receive the rotation-sensing light component to measure a rotation of the optical gyroscope system.
