Abstract
A coupler array device may include an array of couplers arranged in a coupler plane, where each of the couplers couples light between the coupler plane and one or more directions outside of the coupler plane. A coupler array device may further include a pixel switch network to selectively couple light into or out of a selected subset of the plurality of couplers, where the pixel switch network may include one or more pixel-network waveguides and pixel-network switches to couple light between couplers and pixel-network waveguides. The coupler array device may further include one or more feed networks including a feed-line waveguide and one or more feed-network switches to couple light between the feed-line waveguide and at least some of the pixel-network waveguides. Light may be routable between selected couplers and selected feed-line waveguides along selected paths by controlling the pixel-network switches and the feed-network switches along the selected paths.
