Temperature-insensitive Nanobore Fiber Bragg Grating

A fiber Bragg grating based on a novel nanobore fiber is proposed and fabricated by the femtosecond laser direct writing technique and the ultraviolet phase mask exposure technique respectively. The nanobore fiber Bragg grating is temperature-insensitive and has a nanochannel embedded in the fiber core, which can be used for nanofluidic applications.
