Paper Abstract

Fiber Bragg gratings (FBGs) in the center of multimode microfibers (MM-MF) with 10μm diameter were successfully inscribed with point-by-point method and their reflection spectra show peaks over 10dB signal-to-noise ratio (SNR) and less than 0.5nm bandwidth. FBGs on regular size multimode fiber (~60μm core size) shows nearly continuous reflection spectrum. However, when the diameter of the multimode fiber is reduced to ~10μm, its modal volume significantly decreases so that the remaining optical modes are separated by larger propagation constant difference, resulting distinguishable sharp peaks on FBG reflection spectrum. Therefore, MM-MF based FBGs could be practical sensors for simultaneous multi-parameters with outstanding sensitivity and accuracy.
