Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

Laser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations

Scalable Large Field‐of‐view 3D Photoacoustic Ultrasound Imaging With Digital Multiplexing for Human Extremities

Laser &Photonics Reviews, EarlyView.
A digitally multiplexed, large‐aperture photoacoustic and ultrasound imaging architecture is presented to overcome the fundamental limited‐view artifact inherent in conventional arrays. By significantly broadening the structural detection coverage, this scalable platform enables high‐fidelity 3D visualization of human extremities within a single ...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

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 ...
