  • Curved waveguide configuration to suppress mode conversion
    Patent number: 11048042
    Abstract: A photonic integrated circuit may include a substrate and an optical waveguide integrated with the substrate. The optical waveguide may include a bend section, wherein a bend shape of the bend section is defined by a curvature function to suppress waveguide mode conversion.
    Type: Grant

  • Rotation sensor, rotation sensing method, and applications
    Patent number: 10415970
    Abstract: A chip-scale ultrasensitive ring laser gyroscope that utilizes the physics of exceptional points. By exploiting the properties of such non-Hermitian degeneracies, the rotation-induced frequency splitting becomes proportional to the square root of the gyration speed (?1/2), thus enhancing the sensitivity to low angular rotations by orders of magnitudes. At its maximum sensitivity limit, the measurable spectral splitting is independent of the radius of the cavity rings involved. Binary and ternary systems and associated methods are described.
