Fiber Bragg gratings in As2S3 fibers obtained using a 0/−1 phase mask

Abstract We demonstrate the generation of fiber Bragg gratings in As2S3 fibers using a 633 nm HeNe laser and a 0/−1 phase mask. In a 20-micron core fiber, 17-dB reflection was observed at 1545 nm with a linewidth of 0.18 nm. This method is more robust than the transverse holographic method previously demonstrated in these fibers.
