摘要： An apparatus includes a symmetrical wavelength multiplexor (SWM) that includes a first port that receives a depolarized beam of light of a first center wavelength for a first wavelength range. A second port of the SWM receives a second center wavelength of light for a second wavelength range that is greater than the first wavelength range. A third port of the SWM provides a substantially symmetrical wavelength output to drive a fiber optic gyroscope (FOG) in accordance with the second center wavelength. The depolarized beam of light of the first center wavelength travels from the first port to the second port of the SWM and light of the second center wavelength travels from the second port to the third port of the SWM. The SWM mitigates spectral asymmetries between orthogonal axes of the second wavelength.

摘要： A fiber optic gyroscope (FOG) is provided. The FOG comprises a depolarizer that receives light from a light source, a multifunction integrated optic chip (MIOC) and a sensing coil coupled to outputs of the MIOC. The FOG also includes a polarizer coupled between an output of the depolarizer and an input of the MIOC. The polarizer mitigates polarization non-reciprocity (PNR) bias error and enhances the polarization extinction ratio (PER) of the FOG.

摘要： A system includes a light source that generates a coherent output signal. A light stabilizer comprising an optical fiber can be configured to pass one axis of propagation of the coherent output signal from the light source to a Bragg grating to generate a stabilized pump output signal for the system.
