| 英文摘要 | The present invention relates to a VCSEL device comprising an array of VCSELs, a geometrical shape of an emission area (2) of at least some of said VCSELs being non-circular. At least some of said VCSELs having said non-circular emission (2) area are arranged to provide at least two different orientations of said non-circular emission areas (2) in said device. With such a VCSEL device a more homogeneous intensity profile in the far-field is achieved. |
