The project coordinator, Nerea Otero, will present the last results of AIMEN in the field of multiphoton polymerization, with an ultrafast laser, for generating microstructured features on tool-steel inserts. Resolution in the range of few microns, down to 300nm lateral dimension, has been targeted on the optically enhanced surfaces. The microstructured surfaces have been further replicated by injection molding on polymer components of several cm2. The technology aims to simplify the assembly routes for heterogeneously integrated optoelectronics through direct overmolding of the optics on the components, with drastic improvements in cost, productivity and performance.
