Abstract

We report demonstration of a Brillouin dynamic grating (BDG) in a photonic chip. A BDG was characterized in a 6.5 cm long chalcogenide (As2S3) rib waveguide using CW pumps in x polarization and read using a CW probe in y polarization. The measured reflectivity, on–off ratio, and 3 dB bandwidth (f3dB) for the BDG were 0.4%, 28dB, and 6GHz, respectively.
