We report on electrooptical modulation in a photonic crystal slab waveguide resonator which contains a nanostructured second-order-nonlinear optical polymer. The electrooptical susceptibility in the core was induced by high electric-field poling. A square lattice of holes carrying a line-defect was transferred into the slab by electron-beam-lithography and reactive-ion-etching. Applying an external electric modulation voltage to electrodes leads to a linear electrooptical shift of the resonance spectrum based on the electronic displacement polarization in a noncentrosymmetric medium (Pockels-effect). This effect is therefore inherently faster than other electrooptic modulation effects in nanophotonics.
