Jm. Gerard et al., QUANTUM BOXES AS ACTIVE PROBES FOR PHOTONIC MICROSTRUCTURES - THE PILLAR MICROCAVITY CASE, Applied physics letters, 69(4), 1996, pp. 449-451
A GaAs/AlAs planar cavity containing a collection of InAs quantum boxe
s in its core region has been grown in a single step by molecular beam
epitaxy, and processed by electron-beam lithography and reactive ion
etching into pillar microresonators. The optical study by photolumines
cence of these localized light emitters allows a systematic and precis
e determination of the energies of the first confined photon modes of
such microstructures, in good agreement with theoretical estimates. Mo
re generally, such probes facilitate the experimental study of the mod
es of complex photonic microstructures and of the spontaneous emission
alteration they entail on a quasimonochromatic light emitter. (C) 199
