Combining light-emitting elements of differing divergence on the same substrate

Abstract:

An optoelectronic device (10) includes a semiconductor substrate (20) and a monolithic array (100) of light-emitting elements formed on the substrate. The light-emitting elements include a first plurality of first emitters (102, 156), configured to emit respective first beams of light with a first angular divergence, at respective first positions in the array, and a second plurality of second emitters (104, 105, 158), configured to emit respective second beams of light with a second angular divergence that is at least 50% greater than the first angular divergence, at respective second positions in the array.
