Photonic crystals can be used to modify spontaneous emission. Initially, it was proposed to use photonic crystals to inhibit spontaneous emission, but they can be employed to enhance it as well, with significant implications for light emitting diode structures. We show that thin slab 2-D photonic crystals can provide a spontaneous emission enhancement up to F/sub p/=5 and an overall extraction enhancement up of 8 times. We used thin-film InGaAs/InP 2-D photonic crystal at ambient temperature, but the results would apply equally to InGaN thin films.
