摘要： A photon source includes a photon source body including quantum dots, a non-insulating layer overlying and in contact with the quantum dots, and an electrical contact that allows electrically activated emission of radiation from at least one of the quantum dots. An active region is defined within the photon source body such that emission is only collected from a dot or a limited number of dots within the active region.
