Abstract

Strong self-lensing effects have been observed when propagating 35 ps duration, 1.06 µm 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.
