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. |
