Abstract

Kerr-like polymers can be used for all-optical switching in waveguides. χ(3) for the conjugated polymer MP-PPV has been determined (2.7 · 10−11 e.s.u.) by prism coupling into the nonlinear waveguide. As an example for all-optical switching in waveguides, the beam-scanner has been realized with a grating coupler in a nonlinear polymer waveguide made from azo-dye doped poly-methyl methacrylate (PMMA). Material trade-offs for opto-optical switching in waveguides are discussed and the currently known nonlinear polymers are evaluated due to their applicability.
