Abstract
A VCSEL array having a plurality of VCSELs, each having more than two modes, and the optical emission from each of the VCSELs overlaps in a far field of the VCSELs. A VCSEL array having a plurality of VCSELs, each having an aperture size of at least about 6 μm, and the optical emission from each of the VCSELs overlaps in a far field of the VCSELs. A VCSEL array having a plurality of VCSELs, wherein the spectral width of each VCSEL is at least about 0.5 nm, and the optical emission from each of the VCSELs overlaps in a far field of the VCSELs.
