Modelling of stimulated Brillouin scattering in optical fibres

光波系统公司是一家加拿大公司，专注于光子学的模拟和设计工具。他们最畅销的产品是针对光纤通信行业的，包括整个光纤系统的模拟。虽然他们的模拟工具非常全面，但他们一再收到客户的要求，要求他们将受激布里渊散射的物理过程纳入他们的光纤模拟工具中。受激布里渊散射是沿光纤传播的光波和声波相互作用的结果。对于足够强的光信号，这种相互作用可能会导致信号的很大一部分丢失--事实上，它被转换为反向传播的光波--因此可能对光通信系统非常有害。

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.
