Building with light – fabrication and  assembly of micro structures

Two-photon polymerization as a powerful micro fabrication technology for three-dimensional micro structures acting in combination with controlled manipulation of structures with Holographic Optical Tweezers leads to a new all-optical micro fabrication tool. Besides handling and assembling of the generated structures, the development of durable linkage between the individual micro structures are essential. mehr

Replicated micro structures based on two-photon lithography

Requirements towards innovative optical elements can be directly transferred to the corresponding manufacturing processes. High aspect ratios, asymmetric geometries and arrays consisting of randomly arranged basic elements represent a challenge, which cannot be overcome with established fabrication methods. In this context, two-photon lithography offers a promising alternative. mehr
