Claim 9:
10. A vertical cavity surface emitting laser (VCSEL) array comprising:
a first plurality of emitters each having an emission region of a first shape, wherein the first plurality of emitters are positioned on a substrate to emit light that forms a structured light (SL) pattern at a first phase shift in a far-field of the VCSEL array, and wherein the SL pattern has a quasi-sinusoidal distribution in at least one dimension that is based in part on positions of the first plurality of emitters on the substrate and the first shape of each emission region of each of the first plurality of emitters; and
a second plurality of emitters each having an emission region of the first shape, wherein the second plurality of emitters are positioned on the substrate to emit light that forms the SL pattern in the far-field at a second phase shift that is different than the first phase shift, and the quasi-sinusoidal distribution of the SL pattern at the second phase shift is based in part on positions of the second plurality of emitters on the substrate and the first shape of each emission region of each of the second plurality of emitters.
