In this paper we investigate the interaction of THz radiation with intervalence band transitions. The strong nonparabolicity and k-dependence of the transition dipole moment combined with many body effects leads to interesting features that strongly the polartonic branches as the excitation power increases. The numerical results presented can stimulate further experimental investigations for a deeper understanding of the intervalence band coupling scenario and have potential for polaritonic devices.
