All-optical tuning of fano resonances in broken symmetry GaAs metasurfaces

Karl, Nicholas J.; Vabishchevich, Polina V.; Liu, Sheng; Sinclair, Michael B.; Keeler, Gordon A.; Peake, Gregory M.; Brener, Igal B.

We demonstrate ultrafast tuning of Fano resonances in a broken symmetry III-V metasurface using optical pumping. The resonance is spectrally shifted by 10 nm under low pump fluences of < 100 uJ·cm-2.
