Abstract

Official abstract text for this publication.

A light-emitting diode (LED) apparatus comprises a substrate, a first layer formed over at least a portion of the substrate, an active layer formed over at least a portion of the first layer, a second layer formed over at least a portion of the active layer, and at least one waveguide formed below the substrate. A first portion of light from the LED is directed in a first direction and a second portion of light from the LED is directed in a second direction via the waveguide, the second direction being different than the first direction. The apparatus may further comprise a shutter formed at least one of above and below the waveguide, the shutter being adjustable to control an amount of light entering or exiting the waveguide.
