Abstract

We propose and theoretically investigate a hybrid silicon/aluminum nitride waveguide on the SOI platform. The proposed scheme enables both piezomechanical interaction and optomechanical interaction within the hybrid waveguide. The microwave is piezoelectrically coupled to mechanical vibration in the optical waveguide through the deposited aluminum nitride. On the other hand, the light is coupled to the mechanical vibration through the radiation pressure and electrostriction. The simulation results show that near-unity internal conversion efficiency from the microwave domain to the optical domain can be achieved.
