Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.

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 ...

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Chiral Quasi‐BICs Stemming From a Γ‐point Degeneracy

Laser &Photonics Reviews, EarlyView.
Band degeneracies universally exist in 2D periodic systems. However, the studies on the intrinsic properties of those isolated points remain limited. By exploring 3D chiral perturbations, chiral quasi‐BICs are achieved through a Γ‐point degeneracy in resonant metasurfaces with C4 symmetry.

Compact Single‐Shot Incoherent Edge Detection With a Polarization‐Multiplexed Metalens

Laser &Photonics Reviews, EarlyView.
A polarization‐sensitive metalens enables single‐shot incoherent edge detection by generating two polarization‐dependent images and digitally subtracting them to realize a high‐pass optical transfer function. ABSTRACT Edge detection under incoherent illumination is highly desirable for compact vision systems but remains challenging due to the lack of ...
