Abstract
We have dramatically enhanced the photoluminescence intensity emitted from a single quantum well (typically by factors of 3-6) by covering the sample surface with a thin semitransparent metallic film. Using a photolithographi cally prepared gold grating, we show that this enhancement is due to the ex citation of surface plasmons on the metal. By selectively turning off the s urface plasmon excitation via sample or light polarization rotation, the en hancement can be suppressed. (C) 1999 American Institute of Physics.
