A theoretical study on the stimulated Brillouin scattering (SBS) in a sub-wavelength anisotropic waveguide is conducted. The optical, photoelastic, and mechanical anisotropies of the waveguide materials are all taken into account. First, the integral formulae for calculating the acousto-optical coupling coefficients due to the photoelastic and moving interface effects in SBS are extended to an optically anisotropic waveguide. Then, with the extended formulae, the SBSs in an elliptical nanowire…

Lagrangian description of Brillouin scattering and electrostriction in nanoscale optical waveguides

The diffraction of light by sound waves is known as Brillouin scattering. In optical waveguides, Brillouin scattering can arise from both bulk contributions, modelled by photoelasticity, and surface
