Metasurfaces are two-dimensional nanostructures that allow unprecedented control of light through engineering the amplitude, phase, and polarization across meta-atom resonators. Adding tunability to metasurface components would boost their potential

Achieving large tunability of subwavelength resonators is a central challenge in nanophotonics. Here the authors demonstrate refractive index tuning at mid-infrared wavelengths using temperature-dependent control over the low loss plasma frequency in

Recently, Cd_{3}As_{2} has attracted intensive research interest as an archetypical Dirac semimetal, hosting three-dimensional linear-dispersive electronic bands near the Fermi level. Previous studies have shown that single-crystalline Cd_{3}As_{2} h

Phased-array metasurfaces grant the ability to arbitrarily shape the wavefront of light. As such, they have been used as various optical elements including waveplates, lenses, and beam deflectors. Luminescent metasurfaces, on the other hand, have lar

Mechanical strain can modify the structural and electronic properties of methylammonium lead iodide MAPbI3. The consequences of ferroelastic hysteresis, which involves the retention of structural memory upon cycles of deformation, in polycrystalline

We demonstrate a VO2 based phase-change metasurface that self regulates its emissivity in response to the ambient temperature. The mid-infrared emissivity increases to near unity when operating above the insulator-to-metal phase transition temperatur

While phased-array metasurfaces have been used extensively for wavefront shaping of coherent light, their capability to control spontaneous emission is an open question. Here, we demonstrate metalenses that emit focused beams and compare the focusing
