1. A vertical-cavity surface-emitting laser (VCSEL) array, comprising:
a plurality of channels;
a plurality of traces; and
a plurality of emitters, wherein:
a channel, of the plurality of channels, includes a set of emitters, of the plurality of emitters, arranged in a row of emitters,
the channel includes a trace, of the plurality of traces, that has a first trace portion that is closest to an input end of the trace and a second trace portion that is farthest from the input end,
wherein the first trace portion includes a first subset of emitters, of the set of emitters, that are laterally aligned with other emitters of a portion of an adjacent trace, and
wherein the second trace portion includes a second subset of emitters, of the set of emitters, that are laterally offset from other emitters of another portion of another adjacent trace.
