Abstract
Light Emitting Diodes (LED’s) suffer from poor external quantum efficiencies because most light is coupling to modes confined within the semiconductor. With the use of optically small structures it is possible to channel more light into the radiation modes thus increasing the quantum efficiency of the device. In this contribution we will discuss and demonstrate the potential of planar microcavity LED’s.
