Abstract

AbstractThe physics of microcavities have been a subject of intense study over the past 25 years. This work stimulated a large body of experimental and theoretical work on the optimization of the light extraction properties of light‐emitting diodes. Not only has this led to the current high efficiency microcavity LEDs but also to the high brightness LEDs based on other approaches, which are presently available on the market. An overview of the state of the art of planar semiconductor microcavity LEDs will be presented. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
