Nonlocal metasurfaces: universal modal maps governed by a nonlocal generalized Snell's law
Nanophotonics, Volume 14, Issue 23, Page 3851-3860, 02 November 2025.Abstract In this opinion, we describe the potential of an emerging class of flat optics known as “nonlocal metasurfaces” to manipulate light in both real space and momentum space. While the ultimate form of a conventional “local” metasurface can be viewed as a universal generator of any desired waveform from a fixed input wavefront, the ultimate form ...

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems
Laser &Photonics Reviews, Volume 19, Issue 21, November 6, 2025.This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Spectropolarimetry of the BL-Ic SN 2014ad
, 2016 Over the past two decades a clear relation between Gamma-Ray Bursts (GRBs) and some broad-lined Type Ic Supernovae (SNe) has been observed. The use of spectropolarimetry allows us to directly probe the 3D geometry of the unresolved ejecta of SNe, which ...

Optical Spectropolarimetry of Broad Line Active Galaxies [PDF]
, 1999 We present new optical spectropolarimetry of two bright type 1 AGNs. The observations are part of a project on broad line active galaxies in which, through data analysis and modelling, we aim to identify the polarization mechanism and to probe both the ...
