| Popis: | We have demonstrated comprehensive electric field tuning of the Rabi splitting between the excitonic and photonic modes of a superlattice-embedded microcavity. Using photocurrent spectroscopy to measure the coupling between the modes, we have tuned the microcavity to the maximum possible splitting. We have observed a marked increase in the splitting from 4.5 to 11.5 meV, due to the electric-field enhancement of the superlattice exciton’s oscillator strength and the oscillator strength’s subsequent decrease due to the quantum confined Stark effect. As well, we have determined the oscillator strength for the exciton, finding good agreement with theoretical and experimental values. |
