The formation speed of a self-written waveguide structure formed owing to the propagation of surface waves in a photorefractive polymer composite is measured. The formation speed linearly increases with the power of a laser beam. From the measurements of the dynamics of photorefractive grating and the photocurrent output of the polymer, it is revealed that the waveguide structure is formed by a single photorefractive grating, which is identical for the different power levels of the injected pump beam.
