摘要:
An optical waveguide gyroscope includes at least one optical coupler configured to receive a first optical signal at a first port, to transmit a second optical signal to a second port, and to transmit a third optical signal to a third port. The optical waveguide gyroscope further includes a plurality of resonant waveguides optically coupled to the second port and the third port. The resonant waveguides are generally adjacent to one another and optically coupled to one another. At least a portion of the second optical signal propagates from the second port to the third port by propagating through the plurality of resonant waveguides, and at least a portion of the third optical signal propagates from the third port to the second port by propagating through the plurality of resonant waveguides. The at least a portion of the second optical signal propagates through each resonant waveguide of the plurality of resonant waveguides in a clockwise direction and the at least a portion of the third optical signal propagates through each resonant waveguide of the plurality of resonant waveguides in a counterclockwise direction.
