Abstract
Flexographic printing of optical waveguides is a technology primarily suitable for cm-range waveguide structures. So far, these waveguides have been implemented on PMMA substrates, achieving optical attenuations at around 1 dB/cm. In this domain, optical network structures are already available since the waveguide application process widely relies on parallel material transfer. Integrating such waveguide structures as an optical interlayer in PCB has been challenging due to the unsuitable thermal stability of PMMA substrate. With PI as an established substrate in PCB processes, optical cladding structures must be printed to enable optical waveguiding. The first results show a significant attenuation increase compared to PMMA-based waveguides. This research demonstrates and characterizes EOCB based on flexo-printed waveguides. These waveguides are manufactured using a novel fixed-sheet printing machine designated for functional printing. Thus, high infeed accuracy in the single-micron range can be achieved, and so far, unseen material transfer precision can be shown. The printing process for each optical layer is evaluated according to confocal measurements. Waveguide networks are integrated into a demonstration PCB system, and their split ratio and optical attenuation are measured. Finally, use cases such as bidirectional optical couplers for polymer optical fibers are highlighted, which utilize the novel integrated waveguides.
