The interaction of fs laser pulses with hybrid materials is of high interest. Since the triggered reactions are strongly confined to the focal region, the formation of free-form 3D-printed micro-/nanostructures can be easily carried out with highest precision. The method’s appeal is an intrinsic scalability from the 100 nm to the cm regime. For the restoration of diseased or damaged tissue, the growth of cells on 3D porous scaffolds for tissue engineering is a promising approach to generate autologous tissue. The influence of structure type and size is shown for primary human microvascular endothelial cells.

Supercomputing is reaching out to ExaFLOP processing efficiencies, creating fundamental challenges for the way that computing systems are designed and built. The governing topic is the reduction of power used for operating the computer system, and eliminating the excess heat generated from the system. Current thinking sees optical interconnects on most interconnect levels to be a feasible solution to many of the challenges, although there are still limitations to the technical solutions, in particular with regard to manufacturability in high volume.

We present new concepts for micro-optical devices that allow for higher integration and degrees of automation by additive manufacturing. Our two-photon-absorption (TPA) machine achieves surfaces of optical quality and enables rapid prototyping and rapid manufacture of micro-optical components such as lenses, waveguides, and integrated optical components. The fabrication process is compatible with ORMOCER® materials of excellent transmission in the data and telecom regime, but not limited to this class of materials. We introduce a new type of grating coupler, which allows to significantly decrease the overall package size in vertical direction by enabling flat mounted glass fibers. Apart from the higher degree of miniaturization, we discuss a concept to relax the fiber positioning tolerances compared to present grating couplers, which often still require passive and active alignment. The focus of our discussion is on production speed, reliability, automation and reduction of total process steps for fabrication of electro-optical boards.

High-precision 3D printing for biomedical applications

Optical technologies cover a broad range of applications which make use of the generation and the manipulation of light, and they open up a wide field of novel applications when combined with electronics or biologics. Many efforts have been made to develop laser light sources in order to continuously increase their application potential. The interaction of ultra-short laser pulses with polymer or glass materials is of high technological interest. Since the triggered reactions are strongly confined to the focal region, the formation of free-form 3D-printed micro and nano structures can be easily carried out with highest precision.

For biological applications, the appeal of this method is an intrinsic scalability strongly improving the fabrication of, e.g. microfluidic cells, scaffolds for tissue engineering approaches, or drug delivery systems. For the restoration of diseased or damaged tissue the growth of cells on 3D porous scaffolds for tissue engineering (TE) is a promising approach to generate autologous tissue. Scaffold structures should not only have microscopic feature sizes, but also large overall sizes fabricated from biocompatible or biodegradable materials. Appropriate types of functionalization additionally create binding sites for, e.g. biomolecules and/or cells, thus enabling a precise control of cell adhesion, spreading, growth, and differentiation. The scalability of the method ranging from the sub-100 nm regime to the cm range is demonstrated, and the influence of structure type and size has been shown already for primary human microvascular endothelial cells.
