High Stability and Radiation-resistance Broadband Fiber-optic Source

摘要

Two type of output spectrum profile, flat and gauss profile were realized with gain flatten filter and edge filter respectively. For high performance fiber optic gyroscope application, a vary parameters control technology was taken and the less than 0.5 ppml℃ mean wavelength stability and less than 1% output power stability were achieved within operation temperature -45 °C - +70℃ .To developing radiation-resistance broadband source, the erbium-doped fiber radiation characteristic was studied experimentally and the super-fluorescent fiber source configuration parameters and pump laser diode power were optimized. The radiation-resistance super-fluorescent fiber source module was made. Experimental test shows that two type of SFS, include gauss and flat profile spectrum, can stand against more than 50Krad(Si) radiation dose.
