We designed and developed a fabrication method for a polymeric waveguide connecting multiple optical interconnect layers in three-dimensional integrated electro-optical systems, using a series of silicone elastomer stamps. The scalable process is a deterministic printing method, generating optical S-shaped polymeric lightwave coupling for interconnects among separate layers. General characteristics of S-shaped coupling among layers with various separation distances were investigated too. The soft-lithography fabrication process of this coupling interconnection design allows for significant advantages over traditional designs and fabrication methods in terms of insertion loss as well as 3D integration capability, when used in high-bandwidth printed circuit boards.
