A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies
We introduce 3D nanoprinting of gold nanoparticle assemblies and show that their broad optical responses remain reproducible despite structural disorder. This robustness is attributed to ensemble‐averaged plasmonic responses from many local coupling regions.

Photonic nanovoids for tailored optoelectronic response in silicon solar cells
Optoelectronic workflow followed by experimental validation, demonstrating state‐of‐the‐art efficiency gains. Abstract As crystalline silicon (c‐Si) solar cells become thinner to reduce cost and weight, the optical design principles that govern light trapping (LT) must evolve.

ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators
The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Metal/Si Nanowire Arrays for Hot Electron Catalysis
Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile

For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

This study demonstrates the detection of virus‐sized single polystyrene particles in water by leveraging the ultrahigh‐Q nature of low‐contrast bound states in the continuum (BIC) metasurfaces. The resonance properties of silicon BIC metasurfaces—wavelength, linewidth, and amplitude—all exhibit single‐particle sensitivity, representing a unique sensing

A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...
