Abstract
The mean wavelength, spectrum width, and optical power of the output light of an erbium-doped fiber source (EDFS) are key parameters for navigation systems based on navigation-grade and strategic-grade fiber optic gyroscopes (FOGs). We propose a method of simultaneous stabilization for EDFS parameters. The essence of this method is to stabilize the constant values of the mean wavelength and optical power by real-time adjustment of the two laser diodes’ pump ratios during temperature changes using an EDFS double-pass bidirectional optical scheme with the unpumped erbium-doped fiber. The achieved temperature stability of the EDFS mean wavelength as a component of the FOG was 0.32 ppm/◦C, and the spectrum width at half-maximum was more than 16.5 nm.
