The printing process of polymer optical waveguides is a new and uncharted research topic, which the research group OPTAVER is principally involved in. A main consequence of the printing process is the roughness of the interface between core and cladding. This surface between the dielectric media creates scattering in printed waveguides. To simulate this behaviour, standard non-sequential raytracing methods have to be extended with scattering algorithms. Here, scattering power spectra for each incident ray interacting with the rough surface are generated using the perturbation theory. Another task is to connect MID-specific CAD tools with raytracing simulations to create a holistic tool for design and validation of light propagation. This tool is specifically prepared to analyze the manufacturing process of polymer optical waveguides. This technique facilitates new applications in different research and development fields. Comparing the performances of real printed and simulated polymer optical waveguides is one of the major links between the different researchers of this DFG research group.
