This compact technique could be used for augmented reality, trapped ion quantum computers and optogenetic neural stimulator. Beam steering systems have been used for many years for applications such ...

Researchers from the Technical University of Denmark have developed a way to make a chip that focuses on LiDAR for beam steering smaller and more affordable for its multiple uses in different ...

(Nanowerk News) Chip-scale silicon photonics optical phased array (OPA) is widely used in free-space communication. However, due to the limitation of optical device design and manufacture, the ...

MIT researchers have harnessed integrated optical phased array (OPA) technology to develop a type of integrated optical tweezers, akin to a miniature, chip-based “tractor beam”—like the one that ...

GRENOBLE, France – March 8, 2021 – Taking a step toward developing LiDAR systems for widespread commercial applications, CEA-Leti has developed genetic algorithms to calibrate high-channel-count ...

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 ...

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.
