Analysis of teeth of extinct lemurs has revealed fascinating clues to the evolution of humans, a University of Otago study has found.
Lasers are transformational devices, but one technical challenge prevents them from being even more so. The light they emit can reflect back into the laser itself and destabilize or even disable it. At real-world scales, ...
Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they need to have the same color—or frequency—and bandwidth. Changing a photon's frequency requires altering ...
Scientists from the University of Rostock, Germany were able to recreate fundamental physical properties from the realm of elementary particle physics in a photonic system. The results are published in Nature Physics.
Researchers at Penn Engineering have created a chip that outstrips the security and robustness of existing quantum communications hardware. Their technology communicates in "qudits," doubling the quantum information space ...
A team of German and Spanish researchers from Valencia, Münster, Augsburg, Berlin and Munich have succeeded in controlling individual light quanta to an extremely high degree of precision. In Nature Communications, the researchers ...
Femtosecond pulsed lasers—which emit light in ultrafast bursts lasting a millionth of a billionth of a second—are powerful tools used in a range of applications from medicine and manufacturing, to sensing and precision ...
TU Wien (Vienna) has succeeded in making a new type of material usable for chip technology. This enables faster, more efficient computers and new types of quantum devices.
For 40 years, people have used space-based sensors to measure the amount of light coming from the sun, which gives scientists insight into climate change on Earth.
A new publication from Opto-Electronic Advances discusses low-loss chip-scale programmable silicon photonic processors.
