Metasurface‐Enabled Single‐Shot Intensity‐and‐Phase‐Interrogation Surface‐Plasmon‐Resonance Microscopy

Laser &Photonics Reviews, EarlyView.
A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers

Laser &Photonics Reviews, EarlyView.
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Transmission‐Mode Silicon‐Rich Nitride Mie‐Void Metasurfaces in the Visible

Laser &Photonics Reviews, EarlyView.
Transmission‐mode Mie‐void metasurfaces are demonstrated in silicon‐rich nitride, where localized void resonances hybridize with slab‐guided and Fabry–Pérot‐like modes in a finite film, producing a quantified avoided crossing between coupled modes. Controlled void depth tunes the visible transmission spectrum, enabling structural color and spatial ...

Symmetry Breaking Enables Direction‐Selective Power Routing Between Diffraction and Dissipation in Obliquely Metallized Opaque Metagratings

Laser &Photonics Reviews, EarlyView.
Oblique metallization creates one‐sided opaque metagratings that route zero‐order‐hidden optical power between nonzero diffraction and material dissipation. Cross‐sectional‐SEM‐guided models reproduce measured zero‐order spectra and reveal direction‐selective channel exchange governed by morphology and Rayleigh‐order availability.

Scalable Multi‐Target Illusion via a Segmented Spatiotemporal Metasurface [PDF]

Nanophotonics
An electromagnetic kaleidoscope is realized with a segmented spatiotemporal metasurface that transforms one physical aperture into multiple independently controlled false targets. Parallel‐sequence spectral translation codes apparent range and velocity, while segment allocation regulates echo amplitude. Experiments at 5 GHz generate two to five targets

Weak Measurement for Characterizing Effective Jones Matrices of Phase Gradient Metasurfaces

Laser &Photonics Reviews, EarlyView.
Spin dependent deflection from a PB phase gradient metasurface is converted by two dimensional weak measurement into a centroid map, where the amplitude ratio, phase difference, and phase gradient produce distinct spatial features. These effective parameters are then retrieved directly from the centroid response.
