Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

open access: yesLaser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

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

open access: yesLaser &Photonics Reviews, Volume 20, Issue 20, 21 October 2026.
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 ...

Computational Modeling of a Highly Efficient Perovskite Solar Cell Based on Advanced and Affordable Interlayers

open access: yesNano Select, Volume 7, Issue 10, October 2026.
A carbon‐based perovskite solar cell achieves a power conversion efficiency of 20.64% through integrated optical, electrical, and energy band alignment optimization. The device exhibits over 90% optical absorption, low reflectance, and efficient charge transport, highlighting its potential for stable, cost‐effective, and sustainable solar energy ...

Metal/Si Nanowire Arrays for Hot Electron Catalysis

open access: yesSmall, Volume 22, Issue 55, 1 October 2026.
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

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...
