We used intensity-dependent prism coupling of poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) waveguides to measure the nonlinear absorption coefficients and nonlinear refractive indices of these waveguides in the range 700–1200 nm. The material’s strong nonlinearity combined with low linear waveguide losses (<1 dB/cm) led to promising figures of merit and have made it attractive for use in all-optical switching applications at wavelengths of >1150 nm.
