Original Abstract Submitted

a photonics gyroscope comprises a laser and a common intensity modulation unit that outputs an intensity modulated beam, split into a ccw beam having a first power level and a cw beam having a second power level. a first phase modulator (pa) receives the ccw beam, and a second pa receives the cw beam. a variable optical attenuator (voa) is coupled to the first or second pa. the ccw beam is coupled into a resonator and the cw beam is coupled into the resonator. a first detector receives the ccw beam and a second detector receives the cw beam from the resonator. a ccw control loop locks the ccw beam, and a cw control loop locks the cw beam, to resonance peaks. the voa receives a feedback loop signal to aid in balancing power levels between ccw and cw beams to eliminate a rate signal at an intensity modulation frequency.
