Systematic Design of Wide-Bandwidth Photonic Crystal Waveguide Bends With High Transmission and Low Dispersion

We identify factors affecting transmission and dispersive properties of photonic crystal waveguide (PCW) bends, using 2-D simulations and present a method for systematic design of PCW bends to achieve high transmission and low dispersion over large bandwidths. The bends presented here have higher bandwidth and lower dispersion than bends already reported.
