Abstract:
1. An optical waveguide gyroscope comprising 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 plurality of resonant waveguides comprises at least two resonant waveguides comprising a first resonant waveguide configured to allow light to propagate along the first resonant waveguide in a first path and a second resonant waveguide adjacent to the first resonant waveguide and configured to allow light to propagate along the second resonant waveguide in a second path, wherein the first resonant waveguide and the second resonant waveguide are optically coupled in a way that at least a portion of light propagates either successively through the first resonant waveguide along the first path in a clockwise direction and through the second resonant waveguide along the second path in a clockwise direction or successively through the first resonant waveguide along the first path in a counterclockwise direction and through the second resonant waveguide along the second path in a counterclockwise direction.
