Paper Abstract

Tuning of the vacuum Rabi exciton-photon coupling in semiconductor quantum microcavity structures by external electric and magnetic fields is presented. Contrasting effects due to the two external perturbations are found, principally due to the decrease of exciton oscillator strength in electric field and increase of oscillator strength in magnetic field. The strong coupling limit is easily achieved in these high quality structures with line widths on resonance as small as 1 meV. In addition to the tuning phenomena, the effects of exciton Zeeman splitting on the spectra and unexpected linewidth narrowing phenomena on resonance are reported.
