Abstract

Simultaneous confinement of optical and mechanical modes is a requirement for an efficient Brillouin effect. In silicon-on-insulator (SOI) waveguides this challenge is solved by removing the silica under-cladding. Here we show that subwavelength engineering of the longitudinal and transversal geometries facilitates independent control of the photonic and phononic modes, hence allowing for strong Brillouin scattering. Here, we present a suspended silicon waveguide where a subwavelength lattice of lateral arms is used to separate the waveguide core from a phononic crystal.
