Abstract
An arrangement for the optical coupling of optical and/or opto-electronic components in free-beam technique includes a lens that is integrally formed with a semiconductor wafer. The semiconductor wafer simultaneously serves as an adjustable carrier. A planar Fresnel lens structure, Fresnel zone plate structure or holographic lens structure may be incorporated into the semiconductor wafer. The coupling arrangement of the invention is employed in light wave guide components and particularly laser modules.
