Abstract

See full text

A vertical cavity surface emitting laser (VCSEL) array may comprise a first subset of VCSELs of a plurality of VCSELs, and a second subset of VCSELs of the plurality of VCSELs. One or more first beams to be emitted by the first subset of VCSELs, when the VCSEL array is powered, and one or more second beams to be emitted by the second subset of VCSELs, when the VCSEL array is powered, may have different patterns of areas of energy intensity. The different patterns of areas of energy intensity may include respective areas of high energy intensity and respective areas of low energy intensity.
