Shifting colors for on-chip photonics

Nov 24, 2021 (Nanowerk News) The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks...

Artificial intelligence, hardware innovations boost confocal microscope’s performance

Nov 24, 2021 (Nanowerk News) Since artificial intelligence pioneer Marvin Minsky patented the principle of confocal microscopy in 1957, it has become the workhorse standard in life science laboratories worldwide, due to its superior contrast over traditional wide-field microscopy. Yet confocal microscopes aren’t perfect. They boost resolution by imaging just...

New microscopy technique for quantum simulation

Nov 24, 2021 (Nanowerk News) Researchers from the Institute of Laser Physics at Universität Hamburg have developed a new technique for quantum gas microscopy that now allows imaging of three-dimensional quantum systems. In the journal Nature ("Quantum gas magnifier for sub-lattice-resolved imaging of 3D quantum systems"), they report on the...

A seemingly unattainable energy transition

Nov 24, 2021 (Nanowerk News) Researchers from Basel and Bochum have succeeded in addressing an apparently unattainable energy transition in an artificial atom using laser light. Making use of the so-called radiative Auger process, they were the first team to specifically excite it. In this process, an electron falls from...
