INTEGRATED PHOTONICS GYROSCOPE WITH COMMON INTENSITY MODULATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18182217 titled 'INTEGRATED PHOTONICS GYROSCOPE WITH COMMON INTENSITY MODULATION

The photonics gyroscope described in the patent application consists of a laser and an intensity modulation unit that generates an intensity modulated beam split into counterclockwise (CCW) and clockwise (CW) beams with different power levels.

A first phase modulator (PA) receives the CCW beam, while a second PA receives the CW beam.
A variable optical attenuator (VOA) is connected to either the first or second PA to balance the power levels between the CCW and CW beams.
The CCW and CW beams are directed into a resonator, where they interact with the system.
Detectors receive the CCW and CW beams from the resonator to provide feedback for control loops that lock the beams to resonance peaks.
The VOA receives a feedback loop signal to help eliminate rate signals at the intensity modulation frequency.

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.
