“…The inconvenience of the results [44][45][46] is that even in the lowest order, in which nonlinear optical processes are taken into account, the equations are very complicated and require additional simplifying assumptions for their solution. The numerical solutions of these equations were obtained in [69][70][71][72] for the investigation of the optical pulse propagation through a bulk semiconductor under conditions when the photon energy hω is in resonance with the exciton level hω x .…”

The transmission and reflection of an ultrashort laser pulse by a thin semiconductor film under the conditions of resonance excitation of biexcitons by two photons are theoretically investigated. The numerical solutions of the macroscopic equations are found for various values of the film thickness, the detuning from the two-photon resonance, the laser pulse duration, and the intensity. These equations have been obtained in the framework of the generalized bipolariton model. In this model a biexciton is formed from virtual excitons of four kinds and only some of them interact with the light. It is shown that the thin film substantially transforms the incident pulse. For specific conditions, high and narrow transmission and reflection peaks can appear, or even trains of such peaks. In some cases their height can considerably exceed the amplitude of the incident pulse. The results are compared with similar results obtained on the basis of other models.

“…So far, most experiments in SC optics have neglected the phase. Recent experiments [3][4][5] have clearly shown that knowledge of the phase gives new insight into different light-matter interaction regimes, such as polariton beating in bulk SCs, self-induced transmission in SCs, and self-phase modulation (SPM) soliton formation in optical fibers. It must be emphasized though that each of these effects has been studied in a completely different material system until now.…”

Transition between different coherent light–matter interaction regimes analyzed by phase-resolved pulse propagation

et al. 2005

We present phase-resolved pulse propagation measurements that allow us to fully describe the transition between several light-matter interaction regimes. The complete range from linear excitation to the breakdown of the photonic bandgap on to self-induced transmission and self-phase modulation is studied on a high-quality multiple-quantum-well Bragg structure. An improved fast-scanning cross-correlation frequency-resolved optical gating setup is applied to retrieve the pulse phase with an excellent signal-to-noise ratio. Calculations using the semiconductor Maxwell-Bloch equations show qualitative agreement with the experimental findings.
