Classification: CPC G  H | IPC G  H

Claim 0:
1. An optical gyroscope, comprising:
at least one laser configured to generate light beams;
a first optical coupler coupled to a resonator and the at least one laser, wherein the first optical coupler is configured to transmit a first light beam from the at least one laser in a clockwise direction around the resonator;
a second optical coupler coupled to the resonator and the at least one laser, wherein the second optical coupler is configured to transmit a second light beam from the at least one laser in a counter-clockwise direction around the resonator;
a plurality of path length adjustment members coupled to an optical path within the resonator, wherein each path length adjustment member is configured to adjust a respective portion of the optical path within the resonator, wherein at least one path length adjustment member of the plurality of path length adjustment members is positioned about a midpoint of the optical path within the resonator; and
a controller communicatively coupled to the plurality of path length adjustment members, wherein the controller is configured to control the plurality of path length adjustment members based on environmental data received for each respective path length adjustment member, and to modulate an optical path length of the resonator such that at least one of a frequency and wavelength corresponding to the optical path length is modulated outside a bandwidth of the optical gyroscope,
wherein the controller is configured to selectively modulate a phase shift of one path length adjustment member relative to another path length adjustment member so that different phase shifts are modulated between the one path length adjustment member and the another path length adjustment member.
