Abstract
A VCSEL array may include a semiconductor substrate and a plurality of emitters on the substrate that conforms to an emitter pattern. The emitter pattern may be oriented at a non-zero angle to an edge of the substrate and may comprise two or more unit cells arranged to form the emitter pattern. Each unit cell, of the two or more unit cells, may include a same number of emitters, and the two or more unit cells may be arranged to cause a measurement of misalignment associated with two adjacent unit cells, of the two or more unit cells, to satisfy a misalignment threshold.
