Provided is a light emitting diode (LED). The LED, in one embodiment, includes a reflective layer located over a substrate and a quarter wave plate emitter layer located over the reflective layer. The quarter wave plate emitter layer, in this embodiment, is substantially crystalline in nature, and further wherein an extra-ordinary axis of the quarter wave plate emitter layer is located in a plane thereof. The LED, in this embodiment, further includes a transmissive/reflective polarization layer located over the quarter wave plate emitter layer, wherein a transmission direction of the transmissive/reflective polarization layer is oriented at about 45 degrees with respect to the extra-ordinary axis. |
