Researchers from the Department of Food Science (FOOD) at the University of Copenhagen in Denmark are the first in the world to have analysed whole grains with long near-infrared wavelengths using a new type of light source, ...
Research scientists from Jena have produced broadband laser light in the mid-infrared range with the help of liquid-filled optical fibers. The experiment produced proof of a new dynamics of hybrid solitons—temporally and ...
Photonic crystal fibres (PCF) are strands of glass, not much thicker than a human hair, with a lattice of hollow channels running along the fibre. If they are continuously twisted in their production, they resemble a multi-helix. ...
To improve the efficiency of waveguides—devices that guide light on the surface of silicon optical computer chips—a complex balance must be struck. The need for enhanced optical signal processing properties competes with ...
Sending information with the help of light is the future. It requires 'light chips', made of a special glass. Scientists from the UT research institute MESA+ have now managed to equip these light chips - which were already ...
A group of Russian scientists recently presented their research into the process of laser pulse filamentation—the effect produced when a laser beam propagating in air focuses into a filament. The researchers discovered ...
The light generated by researchers from the Max Planck Institute for the Science of Light in Erlangen is more colourful than a rainbow. The scientists couple a low-energy, infrared laser pulse into a photonic crystal fibre ...
A research team from the University of Illinois at Urbana-Champaign has developed a novel, tunable nanoantenna that paves the way for new kinds of plasmonic-based optomechanical systems, whereby plasmonic field enhancement ...
(Â鶹ÒùÔº) —Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different "species," each with ...
A new laser that can show what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below.
