Abstract
We present a theory of ultrafast time-resolved pump and probe spectroscopy in semiconductor microcavities. The numerical solutions are in excellent agreement with experimental data. An analytical study based on the Weisskopf-Wigner approximation gives physical insight into the transient optical nonlinearities of semiconductor microcavites. It is able to explain the physical origin of the unusual transient shifts and asymmetricexcitation-induced dephasing observed experimentally. this theory demonstrates that the nonperturbative regime provides a unique tool for measuring the spectrum of four-particle correlations.
