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 ...

Caltech engineers have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it ...

The LiDAR sets the scene in 3D, which makes it a valuable technology for future sensing and vision systems. Its high cost, however, remains a major obstacle to mass integration. Leveraging silicon ...

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 ...

Though radar is the more prevalent object detection system, the lesser-known ladar -- radar that uses lasers instead of radio frequencies -- produces a more detailed result. The problem though, is ...

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 ...

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 ...

(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 ...

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.
