An Alternative to LEDs for Full-Field Imaging
For some applications, the defining attributes of traditional lasers — high spatial and temporal coherence — can have an adverse effect. High spatial coherence introduces artifacts such as speckle in imaging, which degrades the image. As a result, low-spatial coherence sources such as thermal sources or LEDs are still used in most full-field imaging systems, despite their limited...
Quantum Networks: Photons Hold Key to Data Security
Quantum technology is no longer science fiction. Election results, health data, mobile phone communications, sensitive business information, banking transactions and user IDs — more and more...

Musings on Horses and Quantum Leaps
The Kentucky Derby. The greatest two minutes in sports. Its very name evokes air thick with bourbon and cigar smoke, women’s hats adorned with bows and feathers, sleek thoroughbreds and spectators dressed to the nines. Save, perhaps, for the Masters in April, few sporting events offer a more visually rich experience for TV viewers. Recent advances in consumer display technology have made...

Graphene Plasmons Explored for Nanoscale Control of IR Light
The ability to capture IR light with graphene nanostructures could open new opportunities for ultrasmall and efficient photodetectors, sensors, and other photonic and optoelectronic nanodevices. Near-field image of a rectanglular graphene nanoresonator. Courtesy of CIC nanoGUNE. When light couples to charge oscillations in graphene the result is plasmon — a mixture of light and charge...
