Replication technologies have been recommended as an alternative means of high volume manufacturing of the polymer optical components with low-cost. We demonstrated replication technology as a means of implementing polymer-based MOEMS. To achieve this, a polymer optical bench with embedded electric circuits was designed to integrate the functional planar-lightwave-circuit (PLC)-type optical waveguide devices; the designed packaging structures were realized using a novel fabrication process that incorporated the UV imprint technique. In addition, the detail fabrication steps of the UV imprint process were investigated. The optical bench has v-grooves for the fiber ribbon and the alignment pits for opoelectronic interconnection. The plastic mold for imprinting the designed optical bench was made of UV-transparent perfluorinated polymer material. The designed optical bench was configured on the electric-circuitpatterned silicon substrate. Flip-chip bonded polymer optical waveguide device showed not only a good electric contact but also a coupling loss of 0.9 dB at a wavelength of 1.5 ?m. It was concluded that replication technology has versatile application capabilities in manufacturing next generation optical interconnect systems.
