Patent ID: 11131547

Abstract:
A gyroscope includes a first optical resonator in optical communication with at least one optical waveguide and a second optical resonator in optical communication with the first optical resonator. One of the first optical resonator and the second optical resonator has a power loss rate L greater than zero and the other of the first optical resonator and the second optical resonator has a power gain rate G greater than zero. The at least one optical waveguide, the first optical resonator, and the second optical resonator are configured to be below lasing threshold. The gyroscope further includes at least one optical detector in optical communication with the at least one optical waveguide, and the at least one optical waveguide is configured to receive, from at least one light source, light having an input power Pin at a frequency ωp and to transmit at least a portion of the light having an output power Pout to the at least one optical detector.
