Dynamic theory of picosecond optical pulse shaping by gain-switched semiconductor laser amplifiers

A dynamic theory of semiconductor laser amplifiers is developed that takes into account the coherent time-dependent amplification of an incident optical pulse as well as the nonlinear dynamics of the semiconductor laser when driven be an unbiased injection-current pulse. For suitable time delays between the optical and the electrical pulse, a strongly nonlinear self-induced shortening of the emitted laser pulse is predicted.<
