Abstract
This study describes a novel fabrication technology of multimode polymer optical waveguide, which is named "Large-area Advanced Micro Molding"(LAMM). One of the features of the LAMM method is to replicate the core shape of a waveguide using a silicone rubber mold. The benefits of using the LAMM method are: a low fabrication cost, environment friendliness due to zero emission and organic solvent free fabrication, and possibility to fabricate core sizes (30-120 μm). The multimode waveguide fabricated by the LAMM method provided low optical power loss of 0.06 dB/cm at 850 nm due to a flat boundary between core and cladding. In addition, by using a sandwich structure with high-durability films, the waveguide showed a good stability of <0.1 dB (waveguide length 70 mm) when left at 85 °C / 85% RH for 2000 hours and 0.03 dB/cm for soldering process. Using this fabrication method, we applied waveguides to form Y-branch and create horizontal 90° reflection micromirrors. An optical module using this waveguide with opt-electric devices such as vertical cavity surface emitting laser diodes (VCSELs) and photodiodes (PDs) showed error-free data transmission at the rate of 3.125 Gbps.
