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 ...

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

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 ...

(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 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 ...

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 ...

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 ...

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 ...

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 ...
