A photonic crystal light emitting diode ("PXLED") is provided. The PXLED includes a periodic structure, such as a lattice of holes, formed in the semiconductor layers of an LED. The parameters of the periodic structure are such that the energy of the photons, emitted by the PXLED, lies close to a band...http://www.google.fr/patents/US20030141507?utm_source=gb-gplus-shareBrevet US20030141507 - LED efficiency using photonic crystal structure
