| 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. |
