Abstract

The mode splitting in a system with Dopplerbroadened highdensity twolevel atoms in the presence of magnetic field inside a relatively long optical cavity is studied in the superstrong coupling regime atomscavity coupling strength g sqrt N is near or larger than the cavity freespectral range ΔFSR The effect of a magnetic field applied along the quantization axis is used to break the polarization degeneracy of the cavity and thereby introduce birefringence or Faraday rotation into the medium The cavity modes are further split in the presence of the magnetic field compared with the normal case of the multinormalmode splitting of the twolevel system near the D2 line of 87Rb The dependence of the mode splitting on the magnetic field and the temperature is studied The theoretical analysis according to the linear dispersion theory can provide a good explanation
