Paper Abstract

Strain sensitivities of free, uncoated fiber Bragg gratings at λB ~1535 nm in a SMF28 standard telecommunication fiber and in a highly GeO2 doped photosensitive fiber (F86) were determined at room temperature. Both fibers showed similar strain sensitivities of kSMF28 = (0.7951 ± 0.0041) for the SMF28 and kF86 = (0.7912 ± 0.0023) for the F86 fiber. The stress sensitivities of both fibers were found to be slightly different with the values of (Δλ/F)SMF28 = (1.347 ± 0.006) nm/N for the SMF 28 fiber and (Δλ/F)F86 = (1.309 ± 0.001) nm/N for the F86 fiber.
