Abstract

We experimentally demonstrate a compact microfiber Bragg grating (MFBG) force sensor that offers greater sensitivity under load. The FBG is fabricated by focused ion beam (FIB) milling a microfiber tapered from nonphotosensitive standard single-mode fiber. It is only ∼58μm in length. The force sensitivity of the MFBG is as high as ∼4133nm/N around the resonant wavelength of 1550nm, which is three orders of magnitude larger than that recorded in FBGs inscribed in untapered fibers.
