Photonic Wire Bonding and 3D Nanoprinting in Photonic Integration – from Lab Demonstrations to Production

We give an overview of our research towards exploiting direct-write 3D laser lithography as a tool for advanced photonic integration. The technique offers new perspectives for a wide variety of applications, ranging from photonic wire bonding and multi-chip integration of high-speed communication engines to facet-attached beam-shaping elements and highly efficient coupling in astrophotonic systems. We are currently working on transferring the concept from laboratory demonstrations to industrial manufacturing.
