Abstract

Enhanced transfer efficiency of spontaneous emission, which is the quantum efficiency of the collection of total spontaneously emitted photons, has been revealed with asymmetric AlGaAs planar microcavities containing single GaAs quantum wells at 40 K. The obtained transfer efficiency is as high as ∼15%. An effect of photon reabsorption on the transfer efficiency is also discussed.
