Nonlocal Metasurface Lens for Long-Wavelength Infrared Radiation
Federico De Luca, Sriram Guddala, Michele Cotrufo +3
Dielectric metasurfaces are structured thin films with thickness smaller than the wavelength that aim at replacing and enhancing conventional bulk optical components by structuring…
Demonstration of a Polarization-Agnostic Geometric Phase in Nonlocal Metasurfaces
Adam Overvig, Yoshiaki Kasahara, Gengyu Xu +1
Symmetry-driven phenomena arising in nonlocal metasurfaces supporting quasi-bound states in the continuum (q-BICs) have been opening new avenues to tailor enhanced light-matter int…
Planar chiral metasurfaces with maximal tunable chiroptical response driven by bound states in the continuum
Tan Shi, Zi-Lan Deng, Guangzhou Geng +8
Optical metasurfaces with high-Q chiral resonances can boost light-matter interaction for various applications of chiral response for ultrathin, active, and nonlinear metadevices.…
Spatio-Temporal Coupled Mode Theory for Nonlocal Metasurfaces
Adam Overvig, Sander A. Mann, Andrea Alù
Diffractive nonlocal metasurfaces have recently opened a broad range of exciting developments in nanophotonics research and applications, leveraging spatially extended (yet locally…
Chiral Quasi-Bound States in the Continuum
Adam Overvig, Nanfang Yu, Andrea Alu
Quasi-bound states in the continuum (q-BICs) are resonant states of suitably tailored nanostructures with long optical lifetimes controlled by symmetry-breaking perturbations. Whil…
Roadmap on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-DomÃnguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
