Abstract

The scale factor and other performance of high-precision fiber optical gyro(FOG) is directly related to the performance of the gyroscope using the Fiber source. High-precision fiber optic gyroscope with wide spectrum fiber source used to output spectral width and high power and get high mean wavelength stability. because the fiber gyro scale factor is calibrated by mean wavelength, the mean wavelength stability directly determines the stability of the scale factor of FOG, which is the mean wavelength stability that is the most important parameter in high precision fiber optic gyroscope with wide spectrum source. For erbium doped super-fluorescent fiber light source, the change of average wavelength is mainly due to the change of ambient temperature.

In this paper, based on the theory and concept of photonic crystal, an erbium doped photonic crystal fiber light source based on a double backwards structure is constructed, and the optical path and circuit driving scheme of the erbium doped photonic crystal fiber light source are designed. By optimizing the parameters of erbium-doped photonic crystal fiber, including the length of the erbium-doped photonic crystal fiber, the power loss and pumping power and so on, we finally get the prototype of the erbium doped photonic crystal fiber source. Through the experiment of the light source, the wavelength and the temperature correlation coefficient of the fiber light source reach 1ppm/ degrees.
