Bringing protons up to speed with strong laser pulses – this still young concept promises many advantages over conventional accelerators. For instance, it seems possible to build much more compact facilities.
The Lightwave Research Lab has developed a fast and extremely efficient method for transferring huge amounts of data. The technique uses dozens of frequencies of light to transfer several streams of information over a fiber optic cable simultaneously.
The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence or in bent optical fibre.
An optical fibre about the thickness of a human hair can now carry the equivalent of more than 10 million fast home internet connections running at full capacity.
With a new microscopy technique that uses blue light to measure electrons in semiconductors and other nanoscale materials, a team of Brown University researchers is opening a new realm of possibilities in the study of these critical components, which can help power devices like mobile phones and laptops.
Researchers have developed a way to create photonic time crystals and shown that these bizarre, artificial materials amplify the light that shines on them.
The postdoctoral researcher, a collaborator with the Q-NEXT quantum research center, develops high-tech materials to deliver photon packages of quantum information.
Semiconducting single-walled carbon nanotubes (s-SWCNTs) are being used to develop a third generation of optimized shortwave infrared photodetectors that will improve pixel size, weight, power consumption, performance and cost over photodetectors made from traditional materials.
The absorbed energy is released in the form of rotational motion, causing the molecules to spin like a propeller in the solvent. In a crystalline state, however, the ability to rotate is severely limited, which makes the substances fluoresce strongly under UV light.
By illuminating a sample surface with short laser beam pulses, it is possible to film sequences of various chemical and physical reactions.
