1. An optical structure comprising:
a light source;
a plurality of optical emitters on a common substrate, each configured to emit a light beam from a different respective portion of the common substrate;
an optical power distribution network optically connecting the light source to the plurality of optical emitters, said optical power distribution network including one or more switches;
a receiver comprising at least one photo-detector on the common substrate with the plurality of optical emitters and the optical power distribution network; and
a processing system configured to perform coherent detection;
wherein said one or more switches are configured such that optical power emitted from the light source that enters the optical power distribution network will be emitted from a subset of the plurality of optical emitters; wherein a portion of the emitted optical power is subsequently reflected by an object; and
wherein the reflected optical power is detected by the receiver that provides one or more signals conveyed to the processing system.
