RABI SPLITTING IN CAVITY-EMBEDDED QUANTUM-WELLS UNDER STRONG MAGNETIC-FIELD

We study the interaction of Landau-level transitions with the Fabry-Pe rot mode in a semiconductor microcavity. Using an analytical expressio n for the description of the cavity mode we obtain analytical results for the coupled-mode dispersion relation. The solution of the dispersi on relation as a function of the magnetic field shows that the appeara nce of the strong or weak coupling regime depends on the Landau level index. A qualitative comparison to the experimental data by Tignon et al. [Phys. Rev. Left. 74, 3967 (1995)] is given.
