The talk will present a classification and an overview of mechano-optical coupling structures for photonic integrated circuits (PICs) , which are 3D printed based on Two-Photon Polymerization. It showcases lensed fiber array (LFA) coupling schemes and losses, and provides a demonstration of chip to LFA coupling. It explains the superior quality and speed-up of LFAs with 3D printed lenses using 2-Photon Grayscale Lithography (2GL®). We will show different coupling structures as well as a demonstration of a micro lens array (MLA) on a grating coupler (GC) for beam steering. The process flow from software to printing is also outlined, with an outlook on different future optomechanical coupling mechanisms.
