We demonstrate a light-emitting diode exhibiting 1.7–2.7-fold enhancement in light extraction efficiency compared with that for a planer device. It has a two-dimensional surface grating photonic crystal, which diffracts internal light with a large solid angle into the escape light cone. Due to its shallow grating separated from the active layer and micron order lattice constant, the fabrication process is simple, applicable to arbitrary semiconductor devices, and free from process-induced nonradiative recombinations.
