Soret fishnet metalens antenna. [PDF]
Scientific Reports, 2015 At the expense of frequency narrowing, binary amplitude-only diffractive optical elements emulate refractive lenses without the need of large profiles. Unfortunately, they also present larger Fresnel reflection loss than conventional lenses.

Thermally reconfigurable metalens
Nanophotonics, 2022 Abstract Reconfigurable metalenses are compact optical components composed by arrays of meta-atoms that offer unique opportunities for advanced optical systems, from microscopy to augmented reality platforms. Although poorly explored in the context of reconfigurable metalenses, thermo-optical effects in resonant silicon nanoresonators ...

Stretchable metalens with tunable focal length and achromatic characteristics
Results in Physics, 2021 We propose a stretchable metalens on polydimethylsiloxane (PDMS) substrate. By stretching the stretchable metalens device along x- and y-axis directions, it exhibits highly tunable focal length and achromatic characteristics.
