Phys. Rev. Lett. 69, 3314–3317 (1992)Observation of the coupled exciton-photon mode splitting in a semiconductor quantum microcavityReceived 12 May 1992; published in the issue dated 7 December 1992 The spectral response of a monolithic semiconductor quantum microcavity with quantum wells as the active medium displays mode splitting when the quantum wells and the optical cavity are in resonance. This effect can be seen as the Rabi vacuum-field splitting of the quantum-well excitons, or more classically as the normal-mode splitting of coupled oscillators, the excitons, and the electromagnetic field of the microcavity. An exciton oscillator strength of 4×1012 cm-2 is deduced for 76-Å quantum wells. © 1992 The American Physical Society URL:
