  • Acousto-optic gyroscopes
    Patent number: 11112245
    Abstract: An Acousto-Optic Gyroscope (AOG) consisting of a photonic integrated device embedded into two inherently matched piezoelectric surface acoustic wave (SAW) resonators sharing the same acoustic cavity is disclosed. The micromachined strain-based AOG uses the effective index of the optical waveguide due to the acousto-optic effect rather than conventional displacement sensing.
