Abstract

A light emitting diode (LED) for achieving an asymmetric light output includes a multilayered structure comprising a p-n junction, where at least one layer of the multilayered structure comprises a surface configured to provide a peak emission in a direction away from a normal to a mounting surface, the surface being a top or bottom surface of the layer.
