✦ Synopsis

In studying ultrafast nonlinear optical response of semiconductor system around exciton resonance, coherent propagation effect plays a very important role. In this work, nonlinear coherent propagation of femtosecond optical pulses in semiconductors is studied by time resolved spectroscopy. For ZnP2 sample, measurements at intensities around lmJ/cm 2 lead to slower decay and a clear reduction of the coherent signal amplitude. The experimental result is compared with the numerical calculation of the Maxwell Bloch equations.

## Abstract Nonlinear propagation and wave mixing characteristics of pulses in semiconductor optical amplifiers (SOAs) are analyzed using the finite‐difference beam propagation method (FD‐BPM). From the analyzed output waveform it is found that the peak positions of pulses are shifted to the leadin

Nonlinear propagation of optical pulses through an extended bulk semiconductor is investigated using the coupled semiconductor Maxwell-Bloch equations including excitation induced correlations. For short pulse excitation around the exciton resonance, the theory describes the development of polariton
