Abstract
Birefringence in fiber Bragg gratings (FBGs) can result from two distinct effects that combine with the intrinsic fiber birefringence: the birefringence induced by the UV photo-writing and the birefringence due to a transversal load. In both cases, it leads to polarization dependent loss (PDL) and differential group delay (DGD) inside gratings. Although these parameters are not desired for optical telecommunications applications, we demonstrate here that they can be advantageously used to obtain temperature-insensitive transverse strain measurements with uniform FBGs written into standard single mode fiber, which is not possible through conventional amplitude spectral measurements. Simulated results obtained by means of the coupled mode theory and the Jones formalism as well as experimental results measured by means of a tunable laser source and a polarimeter are presented.
