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...
