Stabilization of Multimode Fiber Link by Simple Insertion of Low-Noise Plastic Optical Fiber

IEEE Photonics Journal
Data transmission in a multimode fiber (MMF) link is significantly improved by simply inserting a low-noise graded-index (GI) plastic optical fiber (POF) between a vertical-cavity surface-emitting laser and standard silica GI MMF, compared with using ...

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Modified POF Sensor for Gaseous Hydrogen Fluoride Monitoring in the Presence of Ionizing Radiations [PDF]

, 2012
This paper describes the development of a sensor designed to detect low concentrations of hydrogen fluoride (HF) in gas mixtures. The sensor employs a plastic optical fiber (POF) covered with a thin layer of glass- like material. HF attacks the glass and

Sensitive cadmium detection using chitosan-coated plastic optical fiber

Next Materials
An optical sensor based on a plastic optical fiber (POF) was developed using PVA-borate-chitosan Coating as a reagent for detecting cadmium in water. The coating is made as a hydrogel containing chitosan that varied in 10 wt% and 20 wt% as an absorber of

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The future of plastic optical fiber [PDF]

NPG Asia Materials, 2009
The number of services providing large-volume information content, such as high-definition movies, continues to increase rapidly. Single-mode glass optical fiber (SM GOF), which has been widely deployed in data trunk lines and pipelines connecting large cities and nations, has already become indispensable as an information transmission medium. However,

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
