Noise Suppression via Gain‐Dispersion‐Managed Nonlinear Amplification in a High‐Power Er‐Fiber Laser

Laser &Photonics Reviews, EarlyView.
Gain‐dispersion‐managed nonlinear pre‐amplification simultaneously suppresses phase and intensity noise, enabling scalable high‐power fiber amplification. The system delivers 102.3 W linearly polarized pulses with 1.19 µJ energy at 85.69 MHz and compresses them to 380 fs. Near‐linear power scaling without evident saturation highlights a practical route

Low‐Crosstalk Silicon Photonic Switch Fabrics for AI Datacenters and High‐Capacity Optical Interconnects: Device‐Level Origins and Mitigation

Laser &Photonics Reviews, EarlyView.
Scaling silicon photonic switch fabrics for AI datacenters is fundamentally constrained by accumulated crosstalk, insertion loss, and device‐level non‐idealities. This work establishes a device‐to‐link‐to‐system framework that connects the physical origins of crosstalk to practical mitigation strategies across device, circuit, and control levels.

Symmetry Breaking Enables Direction‐Selective Power Routing Between Diffraction and Dissipation in Obliquely Metallized Opaque Metagratings

Laser &Photonics Reviews, EarlyView.
Oblique metallization creates one‐sided opaque metagratings that route zero‐order‐hidden optical power between nonzero diffraction and material dissipation. Cross‐sectional‐SEM‐guided models reproduce measured zero‐order spectra and reveal direction‐selective channel exchange governed by morphology and Rayleigh‐order availability.

Raman‐Enabled Platicon Microcomb and Stokes Soliton in 4H‐SiC Microresonator

Laser &Photonics Reviews, EarlyView.
We harness Raman gain in a silicon carbide microresonator to enable efficient platicon microcomb generation in the normal‐dispersion regime. The resulting platicon spans 1500–1700 nm with a pump‐to‐comb conversion efficiency up to 56%. Simultaneous excitation of a Stokes soliton within the same mode family further broadens the Raman–Kerr microcomb ...

Climate‐change‐amplified wind‐related economic losses during Cyclone Harry (2026)

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Cyclone Harry (January 2026) produced significant wind and rainfall impacts across southern Italy. Compared with 1950–1987, present conditions show warmer temperatures and stronger winds, increasing exposure. An estimated 72 million euros of damage are attributable to climate‐driven wind intensification. Abstract Cyclone Harry affected Sicily, Calabria,
