Paper Abstract

This paper presents simulation and experimental results of orientation-dependent transverse load fiber sensors using fiber Bragg gratings written in four-hole suspended core fibers. Resonant peak shifts and splitting of fiber Bragg gratings were studied as functions of the applied transverse load and its orientation. Both simulation and experimental results revealed that response of fiber Bragg grating in suspended core fibers are sensitive to both orientation and magnitude of transverse strains.
