ABSTRACT:
An embodiment is a method and apparatus for a white or full-color light-emitting diode. First single or multiple quantum wells (QWs) at a first wavelength are formed at an active region between a p-type layer and an n-type layer of a light-emitting diode. Multiple passive quantum wells (QWs) are formed within the p-type layer or the n-type layer. The multiple passive QWs are optically pumped by the first or single multiple QWs to generate a desired color.
