Abstract

The stability of the mean wavelength of Er-droped superfluorescent fiber sources with a direct sampling control unit, intended for fiber-optic gyroscope applications, are explored theoretically and experimentally. The mean wavelength variation versus ambient temperature is measured, and the experimental result shows that the mean wavelength is correlated to the sampling voltage, which is in good agreement with theoretical analysis. The thermal effects are modeled to reduce the influence of temperature variation based on the characteristic of monitoring photodiode, and the control algorithms based on the temperature model are implemented in a standard microprocessor system without additional hardware. The results show that the temperature stability of the SFS mean wavelength is better than 1ppm/°C over the entire range of operating temperature, which confirm that this method is effective, and meet the stringent requirements of the FOG.
