ABSTRACT:
A waveguide optical gyroscope is disclosed. The waveguide optical gyroscope includes a laser, two detectors, a set of couplers and a set of waveguides. The laser generates a light beam. A first waveguide guides the light beam to travel in a first direction, and a second waveguide guides the light beam to travel in a second direction. The first and second waveguides are coupled to several ring waveguides via the couplers. The first detector detects the arrival of the light beam traveling from the first waveguide, and the second detector detects the arrival of the light beam traveling from the second waveguide.
