Abstract

The exciton-polariton mode splitting in semiconductor micorcavitires has been studied so far for the constant exciton broadening, which is small enough for the system to be viewed as in strong coupling regime [1]. However, the influence of the exciton broadening on the mode splitting is quite important both for understanding of the exciton-photon interaction in the transition region between strong and weak coupling [2]. and for their applications in high speed optoelectronics. We have observed in the reflection spectra that the mode splitting disappears when an electric field as high as 100 kV/cm is applied [3].
