Non-imaging optical concentrators for low-cost optical interconnect

In this work we report on a non-imaging optical concentrator for high-speed polymer optical fiber (POF), which has applications in chip-to-chip. consumer display, and backplane data transport. High-speed operation places demands on the ability of coupling from large-core media to small apertures typical of 10 Gbps optoelectronics. Design and fabrication of concentrators made by single point diamond turning and injection molding will be discussed, and comparison of experimental data to simulation will show good coupling efficiency with a wide tolerance to fiber misalignment.
