Abstract :
Summary form only given. Recent progress in microfabrication involving, etching processes makes it possible to engineer three-dimensional (3D) nanostructures from MBE-grown planar Fabry-Perot micro-cavities. The optical mode is confined laterally by implementing a thin dielectric (native oxide) aperture layer on top of the cavity spacer. The sample under investigation consists of a 16 period GaAs/AlAs bottom mirror, a /spl lambda/ GaAs spacer, and a 4 period ZnSe/MgF/sub 2/ dielectric mirror on top of the oxide aperture. The aperture diameters range from 1 to 7 /spl mu/m. A high-quality 85 /spl Aring/ InGaAs single quantum well is located in the anti-node of the spacer.
