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…
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…
Dynamical ultrafast all-optical switching of planar GaAs/AlAs photonic microcavities
Philip J. Harding, Tijmen G. Euser, Yoanna-Reine Nowicki-Bringuier +2
The authors study the ultrafast switching-on and -off of planar GaAs/AlAs microcavities. Up to 0.8% refractive index changes are achieved by optically exciting free carriers at 172…
