| titleOfInvention | Method for stabilizing mean wavelength of wide spectrum super-fluorescent optical fiber light source |
| abstract | The invention relates to a method for stabilizing mean wavelength of a wide spectrum super-fluorescent optical fiber light source. The method comprises the step of: letting the wide spectrum super-fluorescent optical fiber light source pass through a fiber which is used for a light source having mean wavelength variable in a parabola manner along with the temperature to obtain a light source spectrum with stable mean wavelength, wherein the light source filter comprises a PTC (Positive Temperature Coefficient) long-period optical fiber grating, a NTC (Negative Temperature Coefficient) long-period optical fiber grating, an optical fiber coil, an optical fiber grating fixing groove and a fiber protective shell. The PTC long-period optical fiber grating, the optical fiber coil and the NTC long-period optical fiber grating are sequentially arranged in the filter protective shell. According to the invention, PTC and NTC optical fiber gratings are adopted as filters to stabilize the super-fluorescent light source having the mean wavelength variable in a parabola manner along with the temperature, and the structure is simple. Compared with a method for stabilizing the mean wavelength by adopting temperature compensation of two metal sheets, the method for stabilizing the mean wavelength of the wide spectrum super-fluorescent optical fiber light source, disclosed by the invention, has the advantages of more matured process and lower manufacturing difficulty. |
