What is claimed is: 1. A light emitting diode comprising:a first semiconductor layer doped with a first dopant, coupled to a first electrode layer;an active layer overlying said first semiconductor layer, capable of emitting light;a second semiconductor layer doped with a second dopant overlying said active layer, said first and second dopants being of opposite type;a second electrode layer on said second semiconductor layer; anda periodically-arranged plurality of holes formed in the second semiconductor layer and extending towards the first semiconductor layer, wherein:the nearest neighbor distance between holes is approximately equal to the wavelength of emitted light;a depth of at least one of the plurality of holes is such that the thickness of said second semiconductor layer at a bottom of said at least one of the plurality of holes is 40 nm;a portion of the second electrode layer is disposed in a region of the second semiconductor layer in which a portion of the plurality of holes are formed;when forward biased, light is emitted from at least a portion of the active layer disposed beneath a portion of the second electrode; andat least one of said first semiconductor layer, said active layer, and said second semiconductor layer composes a group III element and nitrogen.
