Abstract

We demonstrate electromechanical Brillouin scattering in telecom-band integrated photonics platforms based on AlN 1D and 2D optomechanical waveguides. In the former, 16 GHz acoustic modes, which are excited with nanofabricated electromechanical transducers, scatter counterpropagating optical modes into a single anti-Stokes sideband. In the latter, 11 GHz acoustic modes deflect optical modes by 60° in a planar device with integrated transducers, waveguides, and lenses, realizing unprecedented large-angle acousto-optic beam deflection. Our work shows the promises of such new integrated acousto-optic device platforms as efficient interfaces between microwave and optical photons, which may lead to potential applications in on-chip beam steering and routing, optical spectrum analysis, high-frequency acousto-optic modulators, RF or microwave photonics filters and delay lines, as well as nonreciprocal optical dev
