Patent ID: 8148186

Claim:
A method of manufacturing a resonant-cavity light-emitting diode, comprising the steps of: a) forming an array of mesa structures by etching through a resonant cavity; b) forming an n-ohmic contact on a bottom surface of a substrate; c) forming a p-ohmic contact on a portion of a top surface of each of the mesa structures; and d) dicing the array of mesa structures into discrete devices; wherein the resonant-cavity light-emitting diode comprises: a) the substrate; b) a layered mesa structure formed on the substrate, comprising: i) an n-type bottom-side distributed Bragg reflector; ii) a top-side distributed Bragg reflector; iii) a resonant cavity located between the bottom-side distributed Bragg reflector and the top-side distributed Bragg reflector, comprising a light-emitting quantum dot active region including a plurality of self-organized quantum dots; wherein an optical thickness of the resonant cavity is at least 1.5 wavelengths of a main maximum of an emission spectrum; iv) a p-n junction, which is capable of providing electrons and holes to the active region under forward bias; and v) a quantum well, wherein an absorption peak of the quantum well is shifted to a shorter wavelength than a wavelength of a ground state luminescence of the quantum dots; c) the n-ohmic contact; and d) the p-ohmic contact located on the portion of the top surface of the mesa structure.
