The excess waveguiding optical loss of nonlinear optical polymers induced by poling was studied both experimentally and theoretically. The loss was found to be caused by the inhomogeneities in the orientation of the nonlinear optical moiety after poling and is strongly dependent on the uniformity of the guiding and cladding films and the magnitude of the poling field.
