Nanophotonic hybridization of narrow atomic cesium resonances and photonic stop gaps of opaline nanostructures
Philip J. Harding, Pepijn W. H. Pinkse, Allard P. Mosk +1
We study a hybrid system consisting of a narrowband atomic optical resonance and the long-range periodic order of an opaline photonic nanostructure. To this end, we have infiltrate…
Observation of a stronger-than-adiabatic change of light trapped in an ultrafast switched GaAs-AlAs microcavity
Philip J. Harding, Huib J. Bakker, Alex Hartsuiker +4
We study the time-resolved reflectivity spectrum of a switched planar GaAs-AlAs microcavity. Between 5 and 40 ps after the switching (pump) pulse we observe a strong excess probe r…
Broadband sensitive pump-probe setup for ultrafast optical switching of photonic nanostructures and semiconductors
Tijmen G. Euser, Philip J. Harding, Willem L. Vos
We describe an ultrafast time resolved pump-probe spectroscopy setup aimed at studying the switching of nanophotonic structures. Both fs pump and probe pulses can be independently…
Time-resolved resonance and linewidth of an ultrafast switched GaAs/AlAs microcavity
Philip J. Harding, Allard P. Mosk, Alex Hartsuiker +3
We explore a planar GaAs/AlAs photonic microcavity using pump-probe spectroscopy. Free carriers are excited in the GaAs with short pump pulses. The time-resolved reflectivity is sp…
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…
