Abstract:
1. An optical gyroscope comprising: a laser for generating a light beam; a plurality of couplers; a first waveguide, connected to said laser, for guiding said light beam to travel in a first direction; a second waveguide, connected to said laser, for guiding said light beam to travel in a second direction; a first and second ring waveguides coupled to said first and second waveguides, respectively, via two of said plurality of couplers, wherein said first and second ring waveguides are directly optically coupled to each other via another two of said plurality of couplers; a first detector, connected to said first ring waveguide, for detecting the arrival of said light beam from said first waveguide; and a second detector, connected to said second ring waveguide, for detecting the arrival of said light beam from said second waveguide.
