We investigated the beam propagation in a planar polymer waveguide. The conjugated polymer used in our experiments is a solution processable polyarylene vinylene derivative, the DP-PPV/DP-PFV copolymer, which exhibits both a high focusing Kerr-like nonlinearity and an outstanding light and air stability. We report the first experimental observation of spatial solitons in a polymer waveguide. The corresponding spectral broadening could be detected. To obtain a deeper understanding of the experimental results we carried out numerical simulations of the spatial-temporal objects under investigation. The numerical simulations agree quite well with the experimental findings.
