Modelling of stimulated Brillouin scattering in optical fibres

Optiwave Systems Incorporated是一家加拿大公司，专注于光子学模拟和设计工具。他们最畅销的产品是针对光纤通信行业，包括整个光纤系统的仿真。虽然他们的仿真工具非常全面，但客户一再要求他们将受激布里渊散射的物理过程包含到光纤仿真工具中。受激布里渊散射是由沿光纤传播的光和声波之间的相互作用产生的。对于一个足够强的光信号，这种相互作用会导致很大一部分信号丢失——实际上它被转换成向后传播的光波——因此对光通信系统来说可能是非常有害的。

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.
