Optical tuning of dielectric nanoantennas for thermo-optically reconfigurable nonlinear metasurfaces

We demonstrate optically tunable control of second-harmonic generation in all-dielectric nanoantennas: by using a control beam that is absorbed by the nanoresonator, we thermo-optically change the refractive index of the radiating element to modulate the amplitude of the second-harmonic signal. For...
