Numerical approximation for Brillouin fiber ring resonator.

A new method for describing the Stimulated Brillouin Scattering (SBS) generated in a fiber ring resonator in dynamic regime is presented. Neglecting the time derivatives of the fields amplitudes, our modeling method describes the lasers steady-state operations as well as their transient characteristics or pulsed emission. The developed approach has shown a very good agreement between the theoretical predictions given by the SBS model and the experimental results.
