1. An apparatus, comprising:
a collection of emitters on a planar surface of an emitter substrate with irregular distances between the collection of emitters to produce optical beams in a far field with a more even distribution than conventional optical beams in the far field produced by a conventional collection of emitters with regular distances between the conventional collection of emitters;
a collection of receivers on a planar surface of a receiver substrate with irregular distances between the collection of receivers; and
a system substrate hosting the emitter substrate and the receiver substrate;
wherein the emitters are colinear and the receivers are colinear;
wherein the irregular distance between at least a first pair of adjacent ones of the emitters is greater than 17% of a total vertical distance from a bottom of the emitter substrate to a distal emitter of the collection of emitters; and
wherein the irregular distance between at least a first pair of adjacent ones of the receivers is greater than 17% of the total vertical distance from the bottom of the receiver substrate to the distal receiver of the collection of receivers.
