Ultrafast Diffraction Switching using GaAs Metasurfaces

Vabishchevich, P.P.; Vaskin, A.; Karl, Nicholas J.; Reno, John L.; Sinclair, Michael B.; Staude, I.; Brener, Igal

We design a resonant metasurface that uses Mie quadrupole modes to suppress the-1 diffraction order. We show that this suppression can be spectrally tuned using optical pumping on a picosecond timescale.
