Sampled Bragg gratings in chalcogenide (As2S3) rib-waveguides
We have written a sampled Bragg grating into a highly photosensitive chalcogenide (As2S3) rib-waveguide using a scanning Sagnac interferometer. The grating exhibits evenly spaced rejection peaks over a 40 nm bandwidth. We estimate the induced refractive index change of the waveguide to be over 0.03 by matching the measured spectrum to numerical solutions of the coupled mode equations while accounting for an induced chirp. The sampled Bragg grating presented is comparable in strength...[Show more]
