Abstract: An antenna system has a two-dimensional field of view, yet can be implemented on a surface, such as on electronic or photonic integrated circuits. The antenna system includes an array of antennas disposed in a predetermined non-linear pattern and a two-dimensional beamforming network (BFN). The antenna system can be steered/selectively beamformed in two dimensions through beam port selection. The beamforming network is disposed entirely on a single first surface. The beamforming network has a one-dimensional array-side interface disposed on the first surface and a one-dimensional beam-side interface disposed on the first surface. The antennas of the array of antennas are individually communicably coupled to the array-side interface. Segments of the beam-side interface map to respective pixels in the two-dimensional field of view.

Abstract: A multi-beam optical phased array on a single planar waveguide layer or a small number of planar waveguide layers enables building an optical sensor that performs much like a significantly larger telescope. Imaging systems use planar waveguides created using micro-lithographic techniques. These imagers are variants of “phased arrays,” common and familiar from microwave radar applications. However, there are significant differences when these same concepts are applied to visible and infrared light.
