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 ...

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 ...

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 ...

New York, NY--March 19, 2020--While beam steering systems have been used for many years for applications such as imaging, display, and optical trapping, they require bulky mechanical mirrors and are ...

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 ...

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 ...

While cameras continue to get smaller, using a lens to focus light physically limits this process, even with ultra-thin flat lenses on the way, and explains why so many smartphones have protruding ...

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 ...
