Abstract

Summary form only given. We now report numerical simulations of beam propagation in polydiacetylene para-toluene sulfonate (PTS), using measured refractive index values, and demonstrate stable self-trapping and a new phenomenon in which a Gaussian input beam evolves into an expanding spatial ring and interpret these results in the context of the variational model of nonlinear Gaussian beam propagation. We also show preliminary experimental results suggesting the presence of ring formation.
