The Influence of Air-hole Filling Fraction of Photonics Crystal Fibers on Stimulated Brillouin Scattering Slow Light

摘要

The influence of structural parameters of photonic crystal fiber (PCF) on the Stimulated Brillouin Scattering (SBS) slow light by the finite difference time domain method is investigated, the time delay and broadening factor of the pulse are studied for different air-hole filling fractions. The results indicate that time delay increases and broadening factor decreases with air-hole filling fraction increasing. Air-hole filling fraction has less effect on time delay and broadening factor for the same core diameter of PCF.
