Abstract

A new technique to achieve image tuning in a reversible fashion by dielectric metasurfaces, composed of subwavelength silicon resonators, is demonstrated. We show that by controlling the temperature of a metasurface we can tune the encoded transmission pattern. To this end, we have designed and fabricated two sets of nanoresonators composed of non-concentric silicon disks with a hole that exhibit spectrally close sharp Fano resonances and forming a Yin-Yang pattern, with a full control on the contrast.
