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 ...

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 ...

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 ...
