The influence of the TFBG tilt angle on the spectral response

Abstract

Periodic fiber structures generally referred to as fiber Bragg gratings are of increasing interest to sensor designers. In recent years, structures in which the phase planes are not perpendicular to the fiber axis have appeared. The paper is devoted to modeling the dependence of the TFBG spectral response on the phase plane tilt angle. The article also contains measurement results of gratings produced on the basis of the model.
