Abstract

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 n g > 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.

  9. At negative k[Re(k)d/(2π)=−0.38] there are also two evanescent modes, one of which decays with z. It has a field in which the f+/- are switched, and it therefore does not match the forward-propagating slow mode well; we therefore ignore it in our qualitative description, and indeed it plays virtually no role in the coupling.
