Abstract:
1. An illuminator module comprising: a) at least one array comprising a plurality of Vertical Cavity Surface Emitting Lasers (VCSELs), the VCSELs emitting light collectively in a direction perpendicular to an emission surface of the array that comprises a plurality of emission windows in a first contiguous metallized layer located on the emission surface of the array, each emission window being substantially aligned with a respective VCSEL of said array, wherein said first metallized layer in electrical contact with the VCSELs provides a common first electrical contact, and a second metallized layer in electrical contact with the VCSELs and located on an opposing non-emission surface provides a common second electrical contact, respectively, to the at least one array; b) a trench located on the non-emission surface of the array, said trench electrically isolating the second electrical contact of the array from an electrical contact region located on the non-emission surface; and c) an electrically conducting path connecting the first electrical contact located on the emission surface to the electrical contact region located on the non-emission surface, such that the first electrical contact and the second electric contact are coplanar and accessible on the non-emission surface for surface mounting.
