Abstract
Method and apparatus embody a rotation sensor including one or more ring lasers designed to utilize a nonlinear Sagnac effect, a passive waveguide arrangement, and a photodetector arrangement to receive the outcoupled light and to detect rotation of the sensor; wherein these components are arranged into a monolithically integrated optoelectronic integrated circuit on a single substrate. The method and apparatus can include seeding a stable, rotation -insensitive, strong (driving) wave using a single-frequency edge emitting laser monolithically integrated on the same substrate.
