The growing demand for the Internet of Things (IoT) and Artificial Intelligence (AI) need high-speed commu-nication within short-range distances. In the Back-End-Of-Line (BEOL), Single-Mode Waveguide (SMW) with micro-mirror shows the promising application as an Optical Redistribution Layer (O-RDL) connecting photonic-chip at the interposer-level. The presented study shows the potential application of the 2-Photon-Polymerization (2PP) process for fabrication of out-of-plane coupling elements (micro-mirror) for SMW using low-loss Ormocer® hybrid polymers. This fabricated micro-mirror uses as a coupling element to connect the light from RDL to chips or for inter-layer connections at Interposer level. To evaluate the processing time, structural quality, and resolution of the printed micro-mirror, two types of lenses (63x and 25x) and Ormocer® polymers (OrmoComp and OrmoCore) were used. The optimization of the process flow for the micro-mirrors for SMW applications will be described in detail.
