A high-spatial-resolution, i.e., 2.0 mm, strain sensor based on a Rayleigh-scattering-enhanced SMF, i.e., exposed SMF (E-SMF) with direct UV laser, was experimentally demonstrated. The enhancement …
Type II fiber Bragg gratings (FBGs) inscribed with femtosecond ( f s) laser possess significant potential for high temperature sensing. In this work, we propose and demonstrate a method for fabrica…
We propose and demonstrate a highly birefringent fiber Bragg grating (Hi-Bi FBG) fabricated for the simultaneous measurement of strain and temperature. A birefringence of up to 2.96 × 10-4 was cre…
