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

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 distance between ...

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 ...
