Wide bandwidth photonic crystal waveguide bends

We identify factors affecting transmission and dispersive properties of photonic crystal waveguide (PCW) bends and show how they can be varied in a systematic manner to achieve wide bandwidth bends with high transmission and low dispersion. Our experiments show around 12 nm of bandwidth increase as compared to simple bends in a PCW at low group velocities. The bandwidth increase at high group velocities is more than 30 nm.
