Process Development for Digital Fabrication of Radio Frequency Transmission Lines with Off-the-Shelf Equipment

This paper explores the potential of digital fabrication of radio frequency (RF) transmission lines for driving electro-optical devices in photonic integrated circuits. The focus lies on utilization of readily available off-the-shelf equipment. This research focuses on the development and optimization of digital fabrication techniques tailored specifically for RF transmission lines. The presented methodologies pave the way for a more inclusive and accessible landscape in the field of RF components additive on demand fabrication, facilitating advancements in communication systems and technology. In this paper, we employ both inkjet printing and extrusion printing techniques to explore the potential for fabricating coplanar waveguide (CPW) transmission lines.
