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 ...

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 ...

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 ...

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 ...

Narrow Main Beam, Low Side Lobes! High-Performance Electro-Optic Beam Steering with Thin-Film Lithium Niobate Optical ...

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.

A KAIST research team developed a silicon optical phased array (OPA) chip, which can be a core component for three-dimensional image sensors. This research was co-led by Ph.D. candidate Seong-Hwan Kim ...

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 ...
