Abstract :
Summary form only given. We present theoretical and experimental results of the nonlinear amplification and propagation of short optical pulses (250 fs) in semiconductor lasers. The theoretical description is based on spatially resolved Maxwell-Bloch-Langevin equations taking into account the waveguiding structure, spatial variations leading to diffraction, self-focusing and carrier diffusion as well as microscopic coupling between the carrier system and the propagating optical fields.
