Planar-optical microstructures will become important for a large variety of future applications ranging from integrated photonic sensors to short distance communication. Hereby polymers offer a various advantages such as electromagnetic immunity, biocompatibility, as well as easy and cheap fabrication capability. They also provide a high flexibility in manufacturing and design compared to their semiconductor counterparts.
We compared different coupling concepts for horizontally and vertically emitting light sources into planar polymer-optical structures including light sources and detectors to form a polymer transmission path. We focus on low-cost, easy-to-fabricate and optically efficient coupling structures. Also, a transmission line is presented which contains a side emitting laser diode coupled to polymer waveguides by self-written-waveguides. As sensing element, a photo diode chip was integrated above a grating coupler. We discuss optical characterization of the components regarding losses and signal propagation.
