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.
