I often wonder if there is something beyond our grasp and perhaps “other-worldly” about elemental Silicon (Si), which is the primary material for most ICs and discrete semiconductors work. Yes, there ...

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 ...

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.
