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 () rib waveguide using CW pumps in polarization and read using a CW probe in polarization. The measured reflectivity, on–off ratio, and 3 dB bandwidth () for the BDG were 0.4%, , and , respectively.
