Abstract
Combining the scattering state approach with a semi-classical model of the exciton inhomogeneous broadening we have modelled the time-resolved transmi ssion spectra of GaN slabs properly taking into account the exciton-polarit on effect. The decay rate of time-resolved transmission is found to decreas e strongly with increase of the thickness of the slab in case of the inhomo geneous broadening. This is not the case if only a homogeneous mechanism of the exciton broadening is taken into account.
