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.

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing
Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Tunable, High Pulse Energy and Narrow Linewidth Gas‐Filled Fiber Laser Across Near‐ and Mid‐Infrared
A cascaded gas‐filled anti‐resonant hollow‐core fiber architecture enables broadly tunable infrared Raman lasers spanning ∼1.4–4.6 µm while maintaining microjoule‐level pulse energies and gigahertz‐level linewidths. The approach combines a wavelength‐tunable pump laser with optimized Raman frequency conversion, providing a compact route to high ...

Multifunctionality in Silicon Photonics Through Temperature‐Driven Inverse Design
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 ...

A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...
