1. A vertical cavity surface emitting laser (VCSEL) array comprising:
one or more first linear VCSELs on a substrate, each of the one or more first linear VCSELs having a respective linear emission region over a first length; and
one or more second linear VCSELs on the substrate, each of the one or more second linear VCSELs having a linear emission region over a second length that is longer than the first length, wherein
the linear emission region of at least one second linear VCSEL of the one or more second linear VCSELs is parallel to an adjacent linear emission region of a respective first linear VCSEL of the one or more first linear VCSELs,
the respective first linear VCSEL is configured to generate a first structured light pattern for illumination of a near-field portion of a local area serviced by the VCSEL array, and
the one or more second linear VCSEL is configured to generate a second structured light pattern for illumination of a far-field portion of the local area.
