Abstract
A method for detecting rotation includes providing a plurality of resonant waveguides generally adjacent to one another and optically coupled to one another. Each resonant waveguide of the plurality of resonant waveguides is configured to allow light to propagate along the resonant waveguide in a planar path. The method further includes propagating light along each path in a clockwise direction or along each path in a counterclockwise direction.

A method of detecting rotation, the method comprising:
- providing a plurality of resonant waveguides adjacent to one another and optically coupled together, wherein each resonant waveguide of the plurality of resonant waveguides is configured to allow light to propagate along the resonant waveguide in a planar path;
- and
- propagating light along each path in a clockwise direction or along each path in a counterclockwise direction.
A method of detecting rotation, the method comprising:
- providing an optical waveguide gyroscope comprising a plurality of resonant waveguides adjacent to one another and optically coupled to one another;
- propagating at least a portion of a first optical signal through the plurality of resonant waveguides such that the at least a portion of the first optical signal propagates through each resonant waveguide of the plurality of resonant waveguides in a clockwise direction;
- propagating at least a portion of a second optical signal through the plurality of resonant waveguides such that the at least a portion of the second optical signal propagates through each resonant waveguide of the plurality of resonant waveguides in a counterclockwise direction.
A method of detecting rotation, the method comprising:
- providing a plurality of resonant waveguides adjacent to one another and optically coupled together, wherein each resonant waveguide of the plurality of resonant waveguides is configured to allow light to propagate along the resonant waveguide in a planar path, wherein the paths of each of the resonant waveguides of the plurality of waveguides are parallel to one another, at least one of the resonant waveguides including a twisted portion optically coupled to an adjacent resonant waveguide;
- and
- propagating light along each path in a clockwise direction or along each path in a counterclockwise direction.
