Paper Abstract

A low loss refractive waveguided mode can be efficiently coupled to Bloch modes in two dimensional array of nanopillars, in a two-level high index membrane structure, according to a numerical study. More specifically, when using a slow Bloch mode above the light line, a wavelength selective, directional extraction can occur from the waveguide to the free space. The main conditions to be achieved, such as phase matching, strength of the coupling, photon lifetime in the photonic crystal, influence of embedding... will be discussed.
