STRL is promoting research on optical phased arrays *1 that can control the direction of a light ray at high speed by applying voltage, toward the realization of AR glasses capable of viewing natural ...

(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 ...

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 ...

As our devices multiply and data demands grow, traditional wireless systems are hitting their limits. To meet these challenges, we have turned to an innovative solution. At the University of Melbourne ...

Fiber sensing scientists from Shenzhen University have developed an encrypted fiber optic tag that can be used for all-optical labeling and recognition of optical transmission channels such as access ...

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 ...

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, ...

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 ...

The lower image is an illustration of the optical phased array, while the upper two panels are scanning electron microscope images of the array (left) and an individual element of the array (right).

WASHINGTON — Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective and high-performance lidar (or light detection and ranging) ...
