Nanoscale optical switch breaks miniaturization barrier
(Phys.org) —An ultra-fast and ultra-small optical switch has been invented that could advance the day when photons replace electrons in the innards of consumer products ranging from cell phones to automobiles.
Excitons: Exotic particles, chilled and trapped, form giant matter wave
Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave.
Scientists enhance light emission in 2D semiconductors by a factor of 100
The molecule 'scanner': The world's smallest terahertz detector
Molecules could soon be "scanned" in a fashion similar to imaging screenings at airports, thanks to a detector developed by University of Pittsburgh physicists.
Revolutionary ultrathin, flat lens: Smart phones as thin as a credit card?
Scientists are reporting development of a revolutionary new lens—flat, distortion-free, so small that more than 1,500 would fit across the width of a human hair—capable in the future of replacing lenses ...
