Abstract

Semiconductors in strong magnet fields exhibit enhanced dipole moments due to reduced dimensionality imposed by the magnetic confinement. Recently, it has been shown that a strong magnetic field applied to a semiconductor quantum-well (QW) microcavity increases the vacuum Rabi splitting (VRS), bringing Landau level transitions into the strong coupling regime [1]. This regime, characterized by a cavity-exciton coupling which dominates over irreversible decay mechanisms, has been the focus of abundant activity since observation of the VRS [2] and time-domain vacuum-field Rabi oscillations (VRO) [3] in semiconductor microcavities.
