Identification of competing ultrafast all-optical switching mechanisms in Si woodpile photonic crystals
Philip J. Harding, Tijmen G. Euser, Willem L. Vos
We present a systematic study of ultrafast all-optical switching of Si photonic band gap woodpile crystals using broadband tunable nondegenerate pump-probe spectroscopy. At pump-pr…

Kerr and free-carrier ultrafast all-optical switching of GaAs/AlAs nanostructures near the three-photon edge of GaAs
Alex Hartsuiker, Philip J. Harding, Yoanna-Reine Nowicki-Bringuier +2
We performed non-degenerate pump-probe experiments on a GaAs/AlAs photonic structure. We switched the photonic properties using the optical Kerr effect and free carriers excited by…
