SYSTEMS AND METHODS FOR AN OPTICAL FREQUENCY COMB STIMULATED BRILLOUIN SCATTERING GYROSCOPE WITH RIGID OPTICAL WAVEGUIDE RESONATOR

摘要

Systems and methods for an optical frequency comb stimulated Brillouin scattering gyroscope with a rigid optical waveguide resonator are provided. In one embodiment, a system comprises:a light source that produces an optical frequency comb comprising a multiple-frequency light field;a rigid optical waveguide resonator coupled to the light source, wherein a recirculating optical frequency comb produced from the optical frequency comb propagates in a first direction around the rigid optical waveguide resonator and generates within the rigid optical waveguide a SBS light field comprising at least one SBS frequency component, and wherein one or more optical frequency components of the recirculating optical frequency comb are locked on resonance peaks of the rigid optical waveguide resonator; andan optical mixer configured to produce an optical beat signal that varies as a function of a frequency difference between the stimulated Brillouin scattering light field and the recirculating optical frequency comb.
