E. Moreau et al., Single-mode solid-state single photon source based on isolated quantum dots in pillar microcavities, APPL PHYS L, 79(18), 2001, pp. 2865-2867
We report the fabrication of a single-mode solid-state single photon source
, based on an isolated InAs quantum dot (QD) on resonance with the fundamen
tal mode of a pillar microcavity. Photon correlation experiments under puls
ed excitation reveal a clear antibunching behavior. We show that a preparat
ion of the single photons in a given quantum state (same spatial mode, same
polarization) can be obtained by placing a QD in resonance with the nondeg
enerate fundamental mode of an elliptical micropillar. (C) 2001 American In
