Abstract

Excitons in self-assembled quantum dots (QD) constitute an ideal two-level system for cavity-QED applications. Unlike atoms, quantum dots do not exhibit random motion; the QD excitons are strongly trapped by the surrounding high bang-gap energy semiconductor. The advanced semiconductor processing techniques allow for reshaping of the semiconductor material in which the QDs are embedded, so that the resulting structure supports high-Q modes with mode volumes approaching the fundamental limit determined by the wavelength of the generated photon.
