VCSEL array with small pulse delay

A method of manufacturing a laser arrangement, the method comprising:

• providing a Vertical Cavity Surface Emitting Laser (VCSEL) array comprising at least two VCSEL sub-arrays, wherein each of the VCSEL sub-arrays comprises a plurality of VCSELs arranged on a substrate, each VCSEL having an optical resonator comprising a first distributed Bragg reflector, an active layer, and a second distributed Bragg reflector, wherein each VCSEL is processed on the substrate, and wherein a current distribution layer is disposed within one of the first distributed Bragg reflector and the second distributed Bragg reflector,
• providing a first electrical contact arrangement having a first contact area contacting the substrate or the current distribution layer, wherein the first electrical contact arrangement comprises at least one first electrical contact contacting commonly to the VCSELs within a respective VCSEL sub-array, of the VCSEL sub-arrays, at the first contact area to the optical resonator of the respective VCSEL via the substrate or via the current distribution layer, and
• providing a second electrical contact arrangement having a second contact area contacting an uppermost layer of the second distributed Bragg reflector, wherein the second electrical contact arrangement comprises a plurality of second electrical contacts, each second electrical contact contacting a respective single VCSEL within the respective VCSEL sub-array, individually, at the second contact area to a semiconductor layer of the optical resonator of the respective VCSEL, wherein the second electrical contacts are arranged to electrically pump the associated VCSEL along a respective current path through the optical resonator of the associated VCSEL between the first contact area and the second contact area via the substrate or the current distribution layer,
• wherein an arrangement of the at least one first electrical contact and the second electrical contacts has at least one symmetry selected from the group of rotation symmetry, mirror symmetry, and translation symmetry, wherein the first electrical contact arrangement and the second electrical contact arrangement are arranged on a same side of the substrate.
