摘要： A resonator fiber optic gyroscope (RFOG) is disclosed that reduces rotation rate error instability. In one embodiment, the RFOG comprises a resonator optical ring cavity, a first light source in optical communication with the ring cavity and configured to generate a clockwise optical signal, and a second light source in optical communication with the ring cavity and configured to generate a counter-clockwise optical signal. The RFOG also includes a first optical component in optical communication with the first light source and the ring cavity. The first optical component is configured to prevent the clockwise optical signal from being back-reflected to the first light source. A second optical component is in optical communication with the second light source and the ring cavity. The second optical component is configured to prevent the counter-clockwise optical signal from being back-reflected to the second light source. In addition, a first optical detector and a second optical detector are optically coupled to the ring cavity.

摘要： A rare-earth-doped-fiber light source with wavelength stability includes a rare-earth doped fiber and an undoped fiber placed in proximity to each other and having the same host material and the same cross-sectional structure, a coupler configured to direct a first portion of pump power from a pump laser to the undoped fiber so the first portion of pump power was twice passed through the coupler; and a wavelength division multiplexer configured to input a second portion of pump power from the pump laser to the rare-earth doped fiber. The rare-earth doped fiber is an active medium for the broadband light source and includes a fiber core doped with rare-earth ions. The undoped fiber includes a rare-earth-dopant-free fiber core. The length of the undoped fiber is one of the same as that of the doped fiber or optimized to match a radiation sensitivity of the doped fiber.

摘要： A resonator fiber optic gyroscope (RFOG) is provided. The RFOG includes a fiber coil, first and second lasers, first and second phase modulators, and a common phase modulator. The first laser generates CW input light for propagation in the CW direction of the fiber coil. The second laser generates CCW input light for propagation in the CCW direction of the fiber coil. The first phase modulator modulates the CW input light with modulation frequency f 1 = (n+0.5)*FSR. The second phase modulator modulates the CCW input light with modulation frequency f 2 = (m+0.5)*FSR so that overlap of major sidebands is avoided. The phase modulation amplitudes of the first and second modulators substantially suppress the optical carrier components of the CW and CCW input light. The common phase modulator is configured to modulate the CW and CCW input light with a common phase modulation frequency and a common phase amplitude.
