(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 ...

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, ...

Future photonic circuits with the capability of high-speed data processing at optical frequencies will rely on the implementation of efficient emitters and detectors on the nanoscale. Towards this ...

Peter Delos, Technical Lead, Bob Broughton, Director of Engineering and Jon Kraft, Senior Staff Field Applications Engineer, all with Analog Devices. With the proliferation of digital phased arrays in ...

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).

The operation of ground stations and phased-array antennas. How SDRs are integrated into ground stations. Issues to be considered when incorporating SDRs into phased-array antennas. Examples of ...

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 ...

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 ...

Micromachining can be used to create a infra-red beam-forming phased array, according to engineers at University of California, Berkeley, who have made a 160 x 160 array on a 3.1 x 3.2mm die that can ...
