Polarization Imaging and Edge Detection with Image-Processing Metasurfaces
Michele Cotrufo, Sahitya Singh, Akshaj Arora +2
Optical metasurfaces have been recently explored as ultrathin analog image differentiators. By tailoring the momentum transfer function, they can perform efficient Fourier-filterin…
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…
Ghost line waves
Massimo Moccia, Giuseppe Castaldi, Andrea Alù +1
Time-harmonic electromagnetic plane waves in anisotropic media can exhibit complex-valued wavevectors (with nonzero real and imaginary parts) even in the absence of material dissip…
Tunable Magnetless Optical Isolation with Twisted Weyl Semimetals
Vladislav Chistyakov, Viktar S. Asadchy, Shanhui Fan +2
Weyl semimetals hold great promise in revolutionizing nonreciprocal optical components due to their unique topological properties. By exhibiting nonreciprocal magneto-optical effec…
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…
Arbitrarily polarized and unidirectional emission from thermal metasurfaces
J. Ryan Nolen, Adam C. Overvig, Michele Cotrufo +1
Thermal emission from a hot body is ubiquitous, yet its properties remain inherently challenging to control due to its incoherent nature. Recent advances in thermal emission manipu…
Roadmap on structured waves
K. Y. Bliokh, E. Karimi, M. J. Padgett +47
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave.…
