| dc.description.abstract | Planar waveguiding of 350-ps pulses, at a wavelength in the region of the long-wavelength tail of the absorption, is observed by coupling by prism into spun films of Rhodamine-B-doped epoxy films. In a 13-?.m-thick film, ?20 modes are supported at 633 nm. The angle of optimum coupling is seen to be intensity dependent; the angle increases with increasing intensity, indicating a positive real component of the material nonlinearity at all wavelengths investigated. The throughput of the guide is also seen to be strongly intensity dependent, indicating a strong intensity dependence of the transmission of the film. The observed behavior is compared with the intensity dependence of the unguided transmission, and the intensity-coupling efficiencies are estimated. As we know the coupling efficiency, we estimate the real component of the nonlinearity to be 7.0 ? 0.5 ? 10?20 m2 V?2 at 616 nm and 5.0 ? 0.5 ? 10?20 m2V?2at 635 nm from the intensity dependence of the coupling angle | en |
