Purcell effect in a disordered photonic crystals

• We demonstrate that disorder in photonic crystals could lead to a modification of spontaneous emission rate in the frequency region corresponding to a photonic band gap (PBG). Depending on the amount of disorder two different regimes of Purcell effect occurs occurs. For weak disorder Purcell enhancement of spontaneous emission occurs at PBG edges, for strong disorder at PBG centre.
