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 ...

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 ...

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 ...

If you want to create a moving light source, you have a few possibilities. One is to mount a light emitter in some kind of mechanical housing — the approach used in, say, theatrical spotlights, which ...

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 ...

“With our system, you can selectively look in a desired direction and at a very small part of the picture in front of you at any given time, by controlling the timing with femtosecond – quadrillionth ...
