Abstract

In this paper we present the results of theoretical characterization of a few-mode birefringent microstructured fiber dedicated for fiber Bragg grating (FBG) inscription. The spectral characteristics of FBGs written (with a nanosecond and femtosecond laser Talbot interferometer setups) in the core region of the investigated fiber are presented and discussed. We compare the experimental results of the polarimetric strain sensitivity with our previously reported data, outlining perspectives for developing a highly sensitive (with strain sensitivity of second order mode two orders of magnitude higher in comparison to fundamental mode), temperature independent, FBG based strain transducer.
