An optical phased array (OPA) is a nonmechanical beam-steering control device with high directivity and deflection efficiency. Due to its high resolution, fast response, and absence of inertia, the ...

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 ...

(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 ...

Optical delay lines are critical for true time-delay beamforming in phased array systems, enabling precise control of signal arrival times across antenna elements to steer beams without ...

SUNNYVALE, Calif.--(BUSINESS WIRE)--Quanergy Systems, Inc., (NYSE: QNGY) a leading provider of LiDAR sensors and smart 3D solutions, today announced that its Optical Phased Array (OPA) technology has ...

Beam steering systems have been used for many years for applications such as imaging, displays and optical trapping, but they require bulky mechanical mirrors and are overly sensitive to vibrations.

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 ...

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 ...
