Optical phased arrays (OPAs) and beam steering technologies represent a transformative approach in photonic systems, offering rapid and reliable control of light propagation without reliance on ...

Taara already uses optical systems to extend high-speed internet to places where traditional infrastructure is difficult to deploy. Its first system, Taara Lightbridge, is now deployed in over 20 ...

In three recent papers, engineers report the first demonstration of optical phased array technology on-chip at both near infrared and blue wavelength with applications in a broad range of research ...

The Defense Advanced Research Projects Agency (DARPA) has demonstrated solid-state optical phased array technology in a microchip, bringing the ability to bend light to the battlefront. Share on ...

UC San Diego electrical engineers have developed the world’s most complex “phased array” – or radio frequency integrated circuit. This DARPA-funded advance is expected to find its way into U.S.
