Abstract:The photosensitive As₂S₃ fiber has two-photon absorption property under the illumination of 800 nm femtosecond laser pulse. A fiber grating is made by the interference of two femtosecond laser pulses in As₂S₃ fiber, and the period of the grating is determined by the angle between the femtosecond laser pulses and the As₂S₃ fiber. The structure and Bragg reflection spectrum of the fiber grating are studied in this paper.

keywords: femtosecond pulsed laser fiber grating Bragg reflection
