Fabrication of Phase-Shifted Fiber Bragg Grating by Femtosecond Laser Shield Method

Abstract

We demonstrated a simple single-exposure method of fabricating phase-shifted fiber Bragg gratings (PSFBGs), in which a non-photosensitive SMF-28 fiber was irradiated by a femtosecond laser beam passing through a uniform period phase mask. The phase-shifted structure in the FBG was formed by shielding a small region of the incident femtosecond laser beam… (More)
