Paper Abstract

It is shown for the first time that strongly directional emission of defined polarization can be achieved from conventional AlGaAs/GaAs double heterostructure surface emitting light emitting diodes (LEDs) via coupling to surface plasmons. By microstructuring the surface, LEDs were fabricated with a beam divergence of less than 4 deg and an increased quantum efficiency. It is demonstrated that the surface plasmon excitation and emission mechanism has the potential to improve the performance of LEDs. In addition, it is shown that this principle can be applied to laser diodes. A controlled outcoming of laser light by a surface plasmon coupling is demonstrated.
