Low-power integrated beam steering switch matrix platform

A device comprising:

• a first waveguide extending at least in part in a first direction;
• a plurality of second waveguides optically coupled to the first waveguide and extending in a second direction different from the first direction;
• a first plurality of optical elements optically configured to switch optical signals from the first waveguide to corresponding waveguides of the plurality of second waveguides;
• a second plurality of optical elements optically coupled to corresponding waveguides of the plurality of second waveguides and configured to switch optical signals traversing the corresponding waveguides to emitters configured to emit received optical signals;
• and
• one or more control elements configured to control the first plurality of optical elements and the second plurality of optical elements thereby causing selection of an individual optical element of the second plurality of optical elements to separably control one or more of emission or sensing from the selected optical element, wherein the one or more control elements comprise a first plurality of control switches configured to control activation of corresponding optical elements of the first plurality of optical elements.
