Abstract
The authors' semiconductor normal-mode-coupling microcavities, each containing a single narrow-linewidth quantum well, exhibit record many-oscillator vacuum-field Rabi splitting (VRS). The question addressed in this paper is whether the vacuum field can be increased sufficiently by reducing the cavity-mode volume, so that a single quantum dot can exhibit VRS similar to an atom in high-finesse cavity. The quantum-dot nanocavity has two advantages: a length close to the theoretical minimum and a much larger dipole moment; these permit strong coupling without an ultra high-Q cavity even for such a short length. The vacuum field can be increased by oxidation of an AlAs layer to form an aperture.
