Move over, Hollywood—science fiction is getting ready to leap off the big screen and enter the real world. While recent science fiction movies have demonstrated the power of artificially intelligent computer programs, such ...
Over the past few years, physicists and engineers worldwide have developed a growing number of advanced optical technologies and photonic devices, which can be used to emit, detect or manipulate light. The ability to easily ...
Nature clearly likes symmetry. Look at your own hands, for example. But sometimes nature produces asymmetric things, and the reasons aren't always clear.
Topology in optics and photonics has been a hot topic since 1890 where singularities in electromagnetic fields have been considered. The recent award of the Nobel prize for topology developments in condensed matter physics ...
Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of Shanghai for Science and Technology.
The fundamental forces of physics govern the matter comprising the universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation—the particle emission from near black ...
In dark skies around the world there unfolds a nightly battle between bats and the nocturnal insects upon which they feast. You'd have thought bats, equipped as they are with echolocation, in which they navigate using sound, ...
When listening to music, we don't just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic ...
The generation of high harmonics from metals opens a link between solid and plasma harmonics. High-harmonic generation (HHG) is the field of creating high-frequency photons from low-frequency lasers. HHG is the cornerstone ...
In a new publication from Opto-Electronic Advances, researchers led by Professor Andrei V. Lavrinenko and Dr. Pavel N. Melentiev from the DTU Fotonik-Department of Photonics Engineering, Technical University of Denmark, Lyngby, ...
