Scientists achieve single-photon imaging over 200 kilometers

A research team led by Professor Pan Jianwei and Professor Xu Feihu from University of Science and Technology of China achieved single-photon 3D imaging over 200 km using high-efficiency optical devices and a new noise-suppression ...

This is what rolling blackouts look like from space

Extreme winter weather hit Texas hard this February. An air mass from the arctic extended deep into the United States from Canada, with disastrous results for the ordinarily warm state. Along with snow and unusually low temperatures, ...

Researchers create novel photonic chip

Researchers at the George Washington University and University of California, Los Angeles, have developed and demonstrated for the first time a photonic digital to analog converter without leaving the optical domain. Such ...

Pumping a nanoparticle to lase at low power

Lasers are used in a range of everyday devices, harnessing the power of light molecules, photons, - lined up to form highly concentrated beams of light—to perform now common tasks such as scanning barcodes and removing ...

Physicists develop printable organic transistors

Scientists at the Institute of Applied Physics at TU Dresden have come a step closer to the vision of a broad application of flexible, printable electronics. The team around Dr. Hans Kleemann has succeeded for the first time ...
