Abstract
An arrangement of two coupled laser diodes comprises first and second two-layer structures, each structure having a strip-shaped laser-active zone, and a middle layer. The first and second two-layer structures are symmetrically constructed relative to the middle layer at opposite sides thereof and directly across from each other so that the strip-shaped laser-active zones in each of the two-layer structures are positioned at a defined spacing directly across from each other and in symmetrical manner with respect to the middle layer. The middle layer is epitaxially deposited with a precisely dimensioned thickness relative to the two coupled laser diodes being employed.
