Abstract

A framework for simulating the elastic modes in waveguides taking into account the full tensorial nature of the stiffness is presented and implemented in an open-source finite element solver, FEniCS. Various approximations of the elastic-wave equation used in the analysis of stimulated Brillouin scattering are studied and their validity and applicability to micron-sized integrated waveguides is discussed.
