  • Abstract
    Strong self-lensing effects have been observed when propagating 35 ps duration, 1.06 mu m wavelength pulses over 5-10 mm distance through thin-film slab waveguides formed from 4BCMU-polydiacetylene. The results are consistent with a negative nonlinear refractive index coefficient (n2) of magnitude 1-2*10-13 cm2 W-1.
