Polarization Extinction in Hollow-Core Fibers Improved

ArXiv

Analysis

This paper addresses a critical challenge in photonic systems: maintaining a well-defined polarization state in hollow-core fibers (HCFs). The authors propose a novel approach by incorporating a polarization differential loss (PDL) mechanism into the fiber's cladding, aiming to overcome the limitations of existing HCFs in terms of polarization extinction ratio (PER) stability. This could lead to more stable and reliable photonic systems.

Hydrogen Localization in Metals Under Thermal Gradients

Published:Dec 29, 2025 21:19

ArXiv

Analysis

This paper presents a computational method to model hydrogen redistribution in hydride-forming metals under thermal gradients, a phenomenon relevant to materials used in nuclear reactors. The model incorporates the Soret effect and accounts for hydrogen precipitation and thermodynamic fluctuations, offering a more realistic simulation of hydrogen behavior. The validation against experimental data for Zircaloy-4 is a key strength.
