Time Crystals May Improve Lasers and Enable 6G Wireless

Electrical, Electronics & Instrumentation

A novel kind of time crystal can amplify light, potentially leading to significantly better lasers and next-generation wireless communications, a new study finds.A normal crystal is a structure of many atoms organized into a regular pattern in space. However, in 2012, Nobel laureate Frank Wilczek conceived of time crystals, in…

Spintronic Transistor Tech in a Vortex Beam

Computer & Information Technology

For decades, scientists have explored spintronics, which manipulate electron spin to theoretically operate more quickly and burn less energy than conventional electronics. Now researchers find that lasers can generate stable patterns of electron spins in a thin layer of semiconductor material, a discovery that may help lead to advanced spin-based…

Aalyria’s Lasers and Routers Could Close the Digital Divide

Electrical, Electronics & Instrumentation

Aalyria, a recent spinout from Google, is trying to build on other companies’ near successes. The company is revamping the software platform from the ambitious-yet-failed startup Loon to optimize and reconfigure networks in real time, using whatever connections are available. Aalyria is combining that tech with free-space lasers originally developed…
