Dynamics of distributed-feedback fiber lasers: effect of nonlinear refraction.
We present a model for the dynamics of distributed-feedback fiber lasers that includes the effect of nonlinear refraction. The model predicts antiphase and in-phase self-pulsations, asymmetric output, and deterministic chaos if the nonlinear refractive index of the fiber material is sufficiently large. Self-pulsations with frequencies of tens to hundreds of megahertz and pulse widths of several nanoseconds are observed in computer simulations.
