An optical system for producing an optical probe beam includes an optical source that generates a free-space optical beam. An optical element is positioned in a path of the free-space optical beam to project the free-space optical beam to generate a projected free-space optical beam. A photonic integrated phased-array component positioned in a path of the projected free-space optical beam to reflect the projected free space optical beam, thereby generating the optical probe beam. The photonic integrated phased-array component comprises a plurality of antenna elements and a substrate positioned proximate to the plurality of antenna elements, wherein the substrate includes a plurality of fan-out electrical connections from at least some of the plurality of antenna elements such that a size of a region comprising the fan-out electrical connections is larger than a size of a region comprising the plurality of antenna elements.
