Liquid core fibers: A data river runs through them

Data and signals can be transmitted quickly and reliably with glass fibers—as long as the fiber does not break. Strong bending or tensile stress can quickly destroy it. An Empa team has now developed a fiber with a liquid ...

New optical hydrogen sensors eliminate risk of sparking

Hydrogen as a clean, renewable alternative to fossil fuels is part of a sustainable-energy future, and very much already here. However, lingering concerns about flammability have limited widespread use of hydrogen as a power ...

New biosensor designed to detect toxins and more

A device from Los Alamos National Laboratory researchers is not quite the Star Trek "tricorder" medical scanner, but it's a step in the right direction. The Portable EnGineered Analytic Sensor with aUtomated Sampling (PEGASUS) ...

Development of a broadband mid-infrared source for remote sensing

A research team of the National Institutes of Natural Sciences, National Institute for Fusion Science and Akita Prefectural University has successfully demonstrated a broadband mid-infrared (MIR) source with a simple configuration. ...

Biosensing with whispering-gallery mode lasers

Whispering-gallery-mode (WGM) microresonators are opening up many new research directions that enable the detection of proteins, enzymes and DNA, down to single molecules. A new class of sensors makes use of active microresonators ...
