Abstract
A full-vectorial finite element based approach is used to find accurate modal solutions for the acoustic modes in a Ge-doped planar silica optical waveguide. To enhance the accuracy of the solution, the existing structural symmetry is exploited and rigorous analyses of the interactions between the guided acoustic and optical modes are performed. The Stimulated Brillouin Scattering (SBS) frequency and the overlaps between the fundamental and the higher order transverse and longitudinal acoustic modes and the fundamental quasi-TE optical mode are presented.
