Efficient slow-light coupling in a photonic crystal waveguide without transition region

White, T. P.; Botten, L. C.; Martijn de Sterke, C.; Dossou, K. B.; McPhedran, R. C.


We consider the coupling into a slow mode that appears near an inflection point in the band structure of a photonic crystal waveguide. Remarkably, the coupling into this slow mode, which has a group index 𝑛𝑔>1000, can be essentially perfect without any transition region. We show that this efficient coupling occurs thanks to an evanescent mode in the slow medium, which has appreciable amplitude and helps satisfy the boundary conditions but does not transport any energy.
