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 ...

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 ...

Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G millimeter-wave communication. The array integrates four independent beamforming ...

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 ...

JASR Systems LLC, La Jolla, California, was awarded an $8,107,308 firm-fixed-price contract for research and development. The contract provides for the development of chip-scale Optical Phased Arrays ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...
