METHOD FOR MANUFACTURING A TREATED OPTICAL FIBER FOR RADIATION-RESISTANT TEMPERATURE SENSOR |
摘要 |
A method for manufacturing a treated optical fiber for a temperature sensor is provided. The method includes a) obtaining an optical fiber from pure silica or doped by one or more elements from among fluorine and nitrogen, b) imprinting, using a femtosecond laser, at least one Bragg grating in the optical fiber to obtain an imprinted fibe, the Bragg grating extending longitudinally in a portion of the imprinted fiber and being suitable for reflecting light waves propagating along the imprinted optical fiber, the laser having a power greater than or equal to 450 mW, and c) annealing at least the imprinted fiber portion to obtain the treated optical fiber. |
