Low-Cost Fabrication of Multimode Optical Waveguides for Optical Interconnects

광 연결을 위한 저가형 멀티모드 광 도파로의 제작

As low-cost optical waveguides of optical interconnects, we fabricate multimode optical waveguides using a molding process The core size of a optical waveguide is 47 ${\mu}{\textrm}{m}$ $\times$ 41 ${\mu}{\textrm}{m}$. We use the photoresist AZ9260 as a master, polydimethyl-siloxane (PDMS) as a mold. In transferring process to polymeric material, we employ a modified micro-transfer molding process. All processes are simple and low-cost.
