Abstract :
Degenerate four wave mixing of light at 1.055 mu m guided in poly(4,6-decadiyne-1,10 diol bis(n- butoxycarbonylmethylurethane)) planar waveguides has been observed. Diffraction efficiencies of up to 24% have been obtained, with a laser peak power of 2 W. Approximately 50% of the nonlinear mechanism can be attributed to the ultrafast molecular hyperpolarisability of the polymer.
