Abstract: An apparatus, a method, and an optical device for generating light. A conductive quantum well junction is positioned between a first electrode and a second electrode. The conductive quantum well junction is configured to enter into a resonant state to inelastically tunneling one or more electrons. The conductive quantum well junction may include a first dielectric layer, a third conductive layer, and a second dielectric layer. The third conductive layer may be positioned between the first dielectric layer and the second dielectric layer. The first dielectric layer may be coupled to the second electrode and the second dielectric layer is coupled to the first electrode.
