A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

Laser &Photonics Reviews, EarlyView.
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

Laser &Photonics Reviews, EarlyView.
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.

Multifunctionality in Silicon Photonics Through Temperature‐Driven Inverse Design

Laser &Photonics Reviews, EarlyView.
Temperature‐conditioned inverse design embeds thermo‐optic reconfigurability directly into compact silicon photonic devices. By co‐optimizing a single geometry at 300 K (T1) and 520 K (T2), the same structure supports distinct optical functions, enabling experimentally verified switching and mode conversion without resonant architectures or additional ...

Photonic nanovoids for tailored optoelectronic response in silicon solar cells

Responsive Materials, EarlyView.
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.

Gravity‐Driven Assembly Dynamics of Liquid Metal Microdroplets for Functional Composite Films

Small, EarlyView.
This article presents a new understanding of the gravitational settling of liquid metal microdroplets in polymer resin films. It employs an experimental and analysis platform for quantification of the process‐structure relationships to inform the dynamics of gravity‐driven assembly in soft circuit architectures. ABSTRACT Liquid metal (LM) microdroplets

Discriminating Between Living and Dead Bacteria With a Field‐Effect Transistor Based on Nano‐Channels

Small, EarlyView.
Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

Small, EarlyView.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.

Monoalcohol‐Directed Shape Control in a Surfactant‐Free Gold Nanoplate Synthesis

Small Methods, EarlyView.
Surfactant‐free monoalcohol syntheses are advantageous in that they yield colloidal nanostructures that are free of persistent shape‐directing agents but at the expense of realizing only spherically‐shaped nanoparticles. In this work, this limitation is overcome using a low‐complexity light‐driven synthetic protocol yielding periodic arrays of gold ...

Interlayer‐Catalyst Method for Metal‐Assisted Chemical Etching of Ultra‐High Aspect Ratio Silicon Nanostructures

Small Methods, EarlyView.
An advanced patterning method is presented for metal‐assisted chemical etching. The interlayer replaces the resist and enables catalyst deposition on a clean interface. The prepared samples show improved performance with a more reproducible etching profile, higher aspect ratio, and increased consistency over a larger area.

Microfluidic Sample Compartmentalization for Biomolecular Concentration Quantification Using a Nanopore Sensor

Small Methods, EarlyView.
We compartmentalize samples into picoliter volumes using a microfluidic device, allowing us to determine biomolecular concentration by counting molecules to depletion within a known volume without calibration. By integrating a nanopore sensor for this counting process, we also obtain real‐time data on the size, shape, and conformation of each ...
