Abstract: A light-emitting diode (LED) for emitting emitted light having a particular wavelength, said LED comprising: (a) at least one n-doped layer; (b) at least one p-doped layer; (c) an active region comprising at least one layer of light-emitting material disposed between said at least one n-doped layer and said at least one p-doped layer, said active region having an average refractive index, calculated by averaging the LED's refractive index across the thickness of the active region; and (d) at least one low refractive index layer disposed within said particular wavelength of said active region, said at least one low refractive index layer having a refractive index below said average refractive index and a thickness sufficient to limit light being emitted into a guided mode of said active region to no more than 10% of said emitted light.

Abstract: Light emitting diodes including low refractive index layers for reducing guided light are disclosed. The light-emitting diodes include at least one n-doped layer, at least one p-doped layer, and an active region disposed between the at least one n-doped layer and the at least one p-doped layer. The active region comprises a light-emitting material. The light-emitting diode further comprises at least one low refractive index layer disposed in or around the active region.
