Ta. Fisher et al., MAGNETIC-FIELD EFFECTS ON THE VACUUM RABI COUPLING IN SEMICONDUCTOR QUANTUM MICROCAVITY STRUCTURES, Surface science, 362(1-3), 1996, pp. 822-825
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.
