The Nonlinear Optics Group studies nonlinear dynamical processes in the realm of optics. Nonlinear means that optical properties of a material are modified by the irradiated light so that a light beam itself modifies the conditions of its propagation. Dynamical refers to short time scales; we routinely deal with picosecond and femtosecond processes. Since the invention of the laser in 1960, nonlinear optics has emerged as a very active research topic in its own right.

Our focus is on the nonlinear interactions between short pulse of light and optical fibers. Given the right conditions, very special pulses called solitons can arise. After their first experimental demonstration in 1980 solitons have found their way into commercial applications in optical telecommunications ca. 2001. Today, as the data-carrying capacity of optical fibers approaches its limitation, they are as topical as ever. We contribute to the quest for new transmission formats which can keep pace with the incessantly
