New Quantum Computing Architecture Could Be Used to Connect Large-Scale Devices

Quantum computers hold the promise of performing certain tasks that are intractable even on the world’s most powerful supercomputers. In the future, scientists anticipate using quantum computing to emulate materials systems, simulate quantum chemistry, and optimize hard tasks, with impacts potentially spanning finance to pharmaceuticals. ....

Study Demonstrates Vertical-Cavity Surface-Emitting Laser of Shortest Wavelength


Study Demonstrates Vertical-Cavity Surface-Emitting Laser of Shortest Wavelength
Written by AZoOpticsDec 22 2020
Scientists from the Chalmers University of Technology, together with collaborators at Technische Universität Berlin, have developed and exhibited the shortest wavelength ever reported for a vertical-cavity surface-emitting laser (VCSEL).

The study could lay the basis for future applications in, for instance, disinfection and medical treatment. The study findings were published recently in the scientific journal
ACS Photonics.
Although there is still much work to be done, especially to enable electrically driven devices, this demonstration provides an important building block for the realization of practical VCSELs covering the major part of the UV spectral range. ....
