Abstract :
In an infinite periodic PhC slab, due to symmetry considerations, Fano resonances at k=0 completely decouple from the external world and their radiative quality factors become infinite despite lying above the light line. Here, we experimentally demonstrate the existence of such resonances at k~0.
