Generation of flat-top waveform by double optical limiting based on stimulated Brillouin scattering.
A method of generating flat-top waveform by double optical limiting based on stimulated Brillouin scattering (SBS) is proposed. The waveforms are numerically simulated by the theoretic model of double optical limiting based on SBS, and the experimental results are in good agreement with the theoretical simulations. There is a peak in the front and a platform in the back of the waveform by single optical limiting, while the top is almost a platform by double optical limiting.
