Experimental And Simulation Analysis Of Stimulated Brillouin Scattering In Continuous Wave Regime

There are basically five nonlinear phenomena that occur in the optical fiber which limits the power or distort the signal in the data transmission. One of the most important is the phenomenon called Stimulated Brillouin Scattering (SBS) as it only requires relatively low pump power for affecting signal power in single and multi-wavelength transmission in DWDM systems, for instance. There are numerous studies of this phenomenon that deal with power threshold determination which represents the limit on the transmit power but many of them are very complex and not very clear. In this work we propose a simple algorithm for the analysis and simulation of Brillouin power threshold by choosing a set-point. The results are obtained via solving the proposed set of coupled differential equations which then are compared to experimental results for Brillouin and Rayleigh scattering and forward power, i.e. residual pump.
