WebAbstract. Stimulated Brillouin scattering (SBS) processes in optical fibers are driven by two optical field components. In most cases, SBS requires that the two fields are co-polarized. However, the process may also be stimulated by two orthogonally polarized optical waves, even though their combined intensity does not include a beating pattern. WebSurface acoustic waves (SAWs) are electro-mechanical waves that form on the surface of piezoelectric crystals. Because they are easy to construct and operate, SAW devices have proven to be versatile and powerful platforms for either direct chemical sensing or for upstream microfluidic processing and sample preparation. capa de projeto
