Abstract

We report on the first experimental demonstration of backward stimulated Brillouin scattering (SBS) in Lithium Niobate on Insulator (LNOI) waveguides. Performing polarization-dependent pump-probe experiments, we successfully quantified both intramodal and intermodal scattering among fundamental modes, showcasing substantial gains up to $G_{B}=$10m$^{-1}$W$^{-1}$. Such large gains on simple waveguides open a pathway for unlocking novel opto-electro-mechanical phenomena within the LNOI platform.
