An ordered emitter array includes a plurality of micro-emitters configured to emit light. A light combiner configured as a partially fused optical fiber bundle has opposed bundle input and outputs ends between which there extends a plurality of constituent optical fibers. Each optical fiber has opposed light-input and light-output ends coinciding with, respectively, the bundle input and output ends. The light-input end of each optical fiber is aligned with a micro-emitter. Collectively, the light-input ends define a combiner input array having an input-array density indicative of the quantity of light-input ends per unit area, while the light-output ends define a combiner output array having an output-array density indicative of the quantity of light-output ends per unit area. While the diameter of each optical fiber remains constant, the optical fibers collectively taper such that the output-array density is higher than the input-array density.
