Abstract

Time-resolved and power-dependent pump-probe spectroscopy determines that two-photon absorption induces a strong blue-shift of coupling resonances in a photonic crystal waveguide. Carrier relaxation times are shortened by the surface recombination, showing potential for all-optical switching.
