Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures
A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency

Parallel Multi‐Target Detection for Quantum LiDAR
Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

Long-period gratings in chalcogenide fibers
Les verres chalcogénures sont des matériaux optiques connus depuis 50 ans. Ils sont fortement non-linéaires, transparents dans l'infrarouge et photosensibles à la lumière visible. Grâce à des percées récentes du côté des procédés de fabrication, leurs applications dans divers domaines sont devenus possibles, notamment dans les capteurs biochimiques, le

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