Paper Abstract

We present examples of two-dimensional photonic crystal band structures which defy the conventional wisdom that a photonic crystal provides optimal confinement for frequencies at the middle of the photonic band gap. This is due to the presence of an ultra-flat photonic band that leads to enhanced confinement in an adjacent band gap at frequencies near the band gap edge and far from midgap.
