On-chip optical fiber-to-nanophotonic waveguide adiabatic coupler [PDF]

AIP Advances
We report a simple design of an on-chip optical fiber-to-nanophotonic waveguide adiabatic coupler. An inverse-tapered waveguide can be fabricated on an etched oxide layer to achieve index-crossing with a tapered optical fiber without severe light leakage

Dispersion controlled highly nonlinear fibers for all optical processing at telecoms wavelengths [PDF]

, 2010
We review our recent progress in the development of lead silicate glass fibers with high nonlinearity and tailored near-zero dispersion at telecommunication wavelengths, encompassing holey, all-solid microstructured and W-type fiber designs.

MOGAD Is the Most Common Cause of Isolated Optic Neuritis in Children

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives The study aimed to characterize the clinical features, etiologies, and outcomes of isolated, first‐time pediatric ON in the post‐MOG‐IgG era. Methods This was a single‐center retrospective cohort study at Texas Children's Hospital of patients diagnosed with first‐time ON between 2018–2024, with follow‐up data collected through 2025.

Tapered optical-fiber-based pressure sensor [PDF]

, 2000
An optical fiber pressure sensor has been developed using a biconically tapered single-mode optical fiber. The sensor has a pressure range of 1265 mbar and a sensitivity of 0.008 dB/mbar. The main attributes of the presented intensity sensor are its ease

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

The use of a fiber comb filter fabricated by a CO2 laser irradiation to improve the resolution of a ratiometric wavelength measurement system [PDF]

, 2012
An edge filter based ratiometric wavelength measurement system is modelled and analysed in this paper. The results confirm that the noise of input signal and photodetectors limit the resolution of the wavelength measurement system.
