利用飞秒激光诱导光纤布拉格光栅（FBG）的自聚焦特性，在普通单模光纤中形成了从光纤芯延伸至包层空气边界的激光修饰区，通过选择性化学刻蚀制备了微孔阵列。通过改变光纤光栅的制作条件和化学蚀刻，可以控制光纤表面有序微孔的形状和大小。该微孔阵列光纤光栅通过测量传输功率变化和布拉格谐振波长位移，证明了其对周围折射率和温度的同时传感能力。
A microhole array in a common single-mode fiber is fabricated by selective chemical etching of femtosecond-laser-induced fiber Bragg grating (FBG), which has a laser-modified region extending from the fiber core to the cladding-air boundary due to laser self-focusing. The shape and size of the orderly microhole on the fiber surface are controlled via changing conditions of FBG fabrication and chemical etching. A simultaneous sensing for surrounding refractive index and temperature is demonstrated by this microhole array FBG through measurement of the transmission power change and Bragg resonant wavelength shift.
