Abstract

We adopt hexagonal optofluidic ring scatterers to built two-dimensional photonic crystal waveguide (PCW) with triangular lattice. By studying slow light effects of varieties of optical optofluidic rings, the thickness of optofluidic ring in X and Z direction, and the moving distance of the first row of scatterers near central waveguide, some relatively optimism results have been founded. In addition, in the process of research, we adopt PWE method to simulation calculation. When the thickness of optofluidic ring changes, the optimization results which n_g equals 47.2120, bandwidth Δλ is 28.5nm and the group velocity dispersion β₂ is 43.3418 ps²/mm. When the moving distance changes, the optimization results we could get that n_g equals 15.6569, Δλ is 92.9nm and β₂ is 7.8202 ps²/mm. This wideband and low dispersion slow light can be used for storage capacity with certain requirements of the optical buffer, optical sensors, etc.
