Modelling of stimulated Brillouin scattering in optical fibres

Optiwave Systems Incorporated is a Canadian company focused on simulation and design tools for photonics. Their top selling products are aimed at the optical fibre communication industry, and include the simulation of entire optical fibre systems. While their simulation tools are very comprehensive, they have received repeated requests from customers that they include the physical process of stimulated Brillouin scattering into their optical fibre simulation tools. Stimulated Brillouin scattering results from the interaction between light and sound waves travelling along the fibre. For an intense enough light signal, this interaction can cause a large portion of the signal to be lost - in fact it is converted to a backward propagating light wave - and thus can be very deliterious for optical communication systems.
