Classification: CPC G  H | IPC G  H

Claim 0:
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 on the common substrate optically connecting the light source to the plurality of optical emitters, said optical power distribution network including a plurality of switches; and
an array of optical receivers on the common substrate with the plurality of optical emitters and the optical power distribution network;
wherein said 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 conveyed to the array of optical receivers configured to perform coherent detection based on the received reflected optical power.
