Addressing and steering of optical-solitary structures in a single feedback experiment with a saturable Kerr nonlinearity — •Holger Zimmermann, Björn Gütlich, and Cornelia Denz — Institut für Angewandte Physik - WWU Münster

Solitary structures are localised spots, which offer interesting approaches to optical information processing due to their applicability as waveguides and their binary features. Challenging for the implementation are interactions between the solitary structures as well as inhomogeneities of the used nonlinearity. To allow application, a method to steer the solitary structures is necessary. We experimentally realise the steering of solitary structures by adding an incoherent white light distribution to a single feedback system with a LCLV (liquid crystal light valve) as a saturable nonlinearity. Due to steering it is possible to create solitary structures at predefined positions and to control their spatial location.
