Abstract

In this paper, methods for Bragg wavelength corrections in Talbot interferometer for FBG inscription are presented. As a result, a significant improvement of FBG inscription is achieved. Experimental results show that minimization of positioning errors of rotation stages, imperfections of Talbot interferometer construction as well as consideration of fiber dispersion, lead to a Bragg wavelength accuracy not worse than in commercially available gratings but within much wider spectral range. Proposed approach can compete in terms of Bragg wavelength accuracy with the recognized as more precise phase mask method.
