An apparatus includes: an optical phased array (eg, on a photonic integrated circuit), a
focusing element, which can be at a fixed position relative to the optical phased array and …

An integrated optical beam steering device includes a planar Luneburg lens that collimates
beams from different inputs in different directions within the lens plane. It also includes a …

An apparatus comprises: a photonic integrated circuit comprising an optical phased array, a
