Abstract
We investigated the effect of magnetic field on the vacuum Rabi coupli ng strength (Omega(HHx)) in very high quality semiconductor quantum mi crocavity structures, Keeping the exciton and photon on-resonance at e ach magnetic held (B) by varying the temperature, we observed an incre ase in Omega(HHx) by a factor of 1.4 when B is increased from 0 to 14T . Using transfer matrix reflectivity simulations we dedused an increas e in exciton oscillator strength of 2.2, in very reasonable agreement with predictions of quantum well exciton calculations, An additional w eaker splitting, attributed to exciton Zeeman splitting (Delta(z)) was also seen. We make a comparison of on and off-resonance spectra at B= 12T.
