| Abstract: | We present a novel photonic crystal waveguide, which leads to a large increase in group index while maintaining a simple design. We report group index values up to 850 with large bandwidth. Through a study of the group velocity dispersion, we show that our structure is ideally suited for dispersion compensation applications. |
