Thin Film 2-d Photonic Crystals High-Performance Light-Emitting Diodes

Abstract

Photonic crystals, artificially created, multi-dimensionally periodic structures are known for a forbidden electromagnetic band gap. For that reason, they 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 Fp=5 and an overall extraction enhancement up of 8 times.
