Rigorous Simulation of Opto-Mechanically Modulated Electromagnetic Micro and Nano-Cavities

Abstract

We report on numerical analysis of opto-mechanical (OM) cavities, with a full description of the rigorous numerical scheme involved, with emphasis on the mechanical stress induced by EM fields. In the future, OM structures are likely to be integrated in planar technology as pumped phonon sources and detectors, as well as phonon processing components (waveguides, splitters, memories) to process information by means of phonons. The solution of the equations governing the light behavior in opto-mechanical cavities is formally addressed by the Transformation Optics (TO) method. Such kind of calculation will help to engineer the coupling and the synchronization of GHz to tens of GHz coherent phonon sources.
