The potential of using, exploiting, and tailoring light for applications has recently achieved a highly developed state that allows to consider the actual century as the "century of the photon" that displaces the last century - the "century of the electron". Photonics is therefore one of the most promising technologies of the future for information processing, biology and medicine. Optical technologies are nowadays already used e.g. in optical data storage as for CDs and DVDs, or in optical communication using optical fibres.

Our vision however, is to use light in a much more general sense for information processing and to realize all-optical information processing. Such an all-optical chip requires to control light in all its features, and especially needs non-trivial transformations that can only be realized using nonlinear optics. Nonlinear optical effects allow to amplify, control and steer light in order to realize complex information processing tasks. They require the understanding and control of nonlinear effects as well as tailoring light for the purpose of application. Using nonlinear optical processing features, we can use light as the carrier of information of the future. Our actual research activities are centered around this vision, based on two major focus lines - nonlinear optical applications in information, biology and medicine, and photonic circuits by light is guiding light.

All activities are comprehensibly introduced in our image brochure, which appeared in 2011 on the occasion of the 10th anniversary of our workgroup.
