Shapeshifting diffractive optical devices
S. L. Oscurato, F. Reda, M. Salvatore +3
In optical devices like diffraction gratings and Fresnel lenses, light wavefront is engineered through the structuring of device surface morphology, within thicknesses comparable t…

Polariton Nanophotonics using Phase Change Materials
Kundan Chaudhary, Michele Tamagnone, Xinghui Yin +14
Polaritons formed by the coupling of light and material excitations such as plasmons, phonons, or excitons enable light-matter interactions at the nanoscale beyond what is currentl…

A mid-infrared biaxial hyperbolic van der Waals crystal
Zebo Zheng, Ningsheng Xu, Stefano Luigi Oscurato +10
Hyperbolic media have attracted much attention in the photonics community, thanks to their ability to confine light to arbitrarily small volumes and to their use for super-resoluti…
