Abstract: An aspect of the disclosure provides for an optical-phased array (OPA) comprising a star coupler coupled to a plurality of grating couplers, wherein the star coupler comprises multiple inputs and multiple outputs. In some embodiments, each output of the star coupler is coupled to a grating coupler of the plurality of grating couplers. In some embodiments, the star coupler is coupled to the plurality of grating couplers by a plurality of optical delay lines. In some embodiments each output of the star coupler is coupled to a grating coupler of the plurality of grating couplers via an optical delay line of the plurality of optical delay lines. In some embodiments, the OPA further includes an optical switch coupled to the multiple inputs of the star coupler, and at least one tunable laser. Another aspect of the disclosure provides a method for steering light using the OPA.
