Abstract
We present theoretical and experimental demonstration of two designs to achieve group velocity insensitive coupling of light from a ridge waveguide to a photonic crystal waveguide. We demonstrate an average improvement of 62% in coupling to low group velocity modes and an average coupling enhancement of 11.5% at large group velocities.
