Abstract
A vertical cavity surface emitting laser (VCSEL) array may include a plurality of VCSELs. A size of an emission area of a first VCSEL, of the plurality of VCSELs, may be different from a size of an emission area of a second VCSEL of the plurality of VCSELs. The first VCSEL may be located closer to a center of the VCSEL array than the second VCSEL. A difference between the size of the emission area of the first VCSEL and the size of the emission area of the second VCSEL may be associated with reducing a difference in operating temperature between the first VCSEL and the second VCSEL, or reducing a difference in optical power output between the first VCSEL and the second VCSEL.
