摘要

将飞秒激光辐照后化学刻蚀(FLICE)技术应用于标准通信光纤，通过硅包层和导芯截面嵌入开丝光栅阵列。第一次提出了二阶和三阶布拉格空气光栅，提供了可到达外包层表面的纳米流体通道。利用位移光纤布拉格光栅对化学腐蚀的响应来优化一种新型的流体折射率传感器。

Femtosecond Laser Opening of Hollow-Filament Arrays: the Fiber Bragg Grating Opto-fluidic Sensor

Femtosecond laser irradiation followed by chemical etching (FLICE) was applied to standard telecommunication fiber, embedding an open-filament, grating array through the silica cladding and guiding core cross-section. Second and third order Bragg air-gratings are presented for the first time, providing nano-fluidic channels accessible to the outer cladding surface. Pishifted fiber Bragg grating responses to chemical etching were used to optimize a novel refractive index sensor for fluids.
