Patent ID: 7560736

Claim:
A Resonant Cavity Light Emitting Diode (RCLED) device capable of emitting radiation having a peak-like profile with a central wavelength (λ), the device comprising: a first active region having a planar form with a top side and bottom side and one or more quantum wells disposed within, wherein the one or more quantum wells are configured to provide energy to stimulate radiation output the RCLED and are located about an anti-node position for a resonant wave of the RCLED; a first chamber adjacent to the top side of the first active region, wherein the first chamber has a thickness such that it extends a first distance from the middle of the first active region; and a second chamber, adjacent to the bottom side of the first active region, including a cladding layer, an electron confining barrier layer, and a tunneling diode layer; wherein the first active region, the first chamber and the second chamber form a primary resonant path that produces electromagnetic radiation with a center wavelength in the infrared region, and wherein the total thickness of the first active region, the first chamber and the second chamber is about or less than 2λ.
