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

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 ...

A wireless system sends data at 25 Gbps over 10 kilometers using controlled light, without using fiber cables or licensed spectrum.

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 ...

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 ...

Most people are familiar with the concept of RADAR. Radio frequency (RF) waves travel through the atmosphere, reflect off of a target, and return to the RADAR system to be processed. The amount of ...

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 ...

(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 ...
