摘要： A multi-core transport system for a resonant fiber optic gyroscope (100) is provided. The transport system has a transport fiber (102, 302, 402, 502) configured to transmit a clockwise signal and a counterclockwise signal, wherein the transport fiber (102, 302, 402, 502) has at least a first core (202) and a second core (204). The first core (202) and second core (204) are configured such that when the first core (202) imparts a first effect on the clockwise signal, the second core (204) imparts a second effect on the counterclockwise signal, wherein the second effect substantially mirrors the first effect. The system further comprises a first coupler (312, 412, 512) configured to optically couple the clockwise signal to the first core (202), and the counterclockwise signal to the second core (204); and a second coupler (314, 414, 514) configured to optically couple the clockwise signal from the first core (202) to a resonator (110), and the counterclockwise signal from the second core (204) to the resonator (110).

In certain embodiments, a system comprises a light source that produces a multiple-frequency light beam based on an optical frequency comb; and an optical fiber resonator coupled to the light source, the multiple-frequency light beam propagating in a first direction within the optical fiber resonator, wherein the multiple-frequency light beam generates stimulated Brillouin scattering (SBS) for a frequency, wherein the Brillouin scattering generates an SBS light beam to propagate in a second direction, the first direction being opposite in direction to the second direction. The system also comprises a servo to control the frequencies of the optical frequency comb to lock a plurality of component frequencies on resonance peaks of the optical fiber resonator; and a mixer that determines a frequency difference between the SBS light beam and the multiple-frequency light beam.

摘要： Multiple resonator fiber optic gyroscope (RFOG) configurations comprising one or more mode filters inside the resonator are adopted to effectively suppress unwanted high order spatial modes which can be a significant source of gyro bias errors. The resonator comprises at least a loop fiber, either two or more in/out coupling elements, and connectors that link elements into a circulating loop. Directional elements may be used to separate output light from input light in some of the embodiments. In all embodiments, mode filters are placed in the resonator to guarantee that the light reaching the photodetector is filtered by at least one mode filter in the resonator at least once. The mode filters may contain both spatial mode filters (such as single mode fibers or waveguides) and polarization mode filters (such as polarizing elements) so that both spatial and polarization mode filtering can be implemented simultaneously.

摘要： Substantially symmetric RFOG configurations for rotation rate sensing using two input/output coupling components. Configurations are disclosed where optical coupling components handles both input and output lightwaves. Reducing the number of input/output coupling components while maintaining a substantially symmetric configuration for the CW and CCW beam reduces losses, prevents realization of bias errors due to asymmetric light paths in the resonator, and produces better signal to noise performance. In addition, the invention discloses systems integrating multiple functions into compact micro-optic devices that are easier to fabricate and package, leading to compact RFOGs with reduced cost and improved manufacturability.
