Abstract

Low-loss monomode waveguides have been produced using polymer thin films extensively doped with a nonlinear organic material. We report the observation of an intensity-dependent birefringence in these waveguides, indicating the presence of a fast-acting intensity-dependent refractive index. The magnitude of the self-focusing coefficient n₂ for these waveguides has been estimated as 6 × 10⁻¹⁹ m²/V².
