A Scalable Platform for Massively Parallel Superconducting Single‐Photon Detection

open access: yesLaser &Photonics Reviews, EarlyView.
One hundred independent superconducting nanowire detectors, each with efficiency up to 80.1–98.3%, are integrated into a single compact system operating below 2.1 K. This parallel architecture supports fully connected multi‐user quantum entanglement distribution, while its scalability opens new avenues in optical quantum computing, QKD networks ...

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Experimental Demonstration of Plasmon‐Enabled Monolithic Bragg Reflectors for Infrared Light via Inverse Design

open access: yesLaser &Photonics Reviews, EarlyView.
Inverse‐designed plasmon‐enabled distributed Bragg reflectors are realized in modulation‐doped monolithic InP, where free‐carrier‐induced complex refractive‐index contrast enables strong infrared reflection without heteromaterial interfaces. Nonuniform layer optimization reduces absorption and improves reflectivity over uniform designs, offering a ...

Carbon sequestration strategies for climate resilience: Sorghum‐based innovations for sustainable agriculture in dryland regions

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is intensifying heat, drought, and food insecurity, threatening dryland farming and carbon management worldwide. We reviewed research on sorghum, a drought‐adapted C4 crop, covering physiology, roots, biomass allocation, soil carbon, bioenergy, breeding, phenotyping, management, and policy.

Scaling turbulence drives the general circulation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous
