Research from Eindhoven University of Technology has shown an improved method of constructing optical fiber arrays, which could significantly improve efficiency and lower the cost of developing photonic chips. The research specifically addresses improvements to optical fiber coupling, which is used to guide light in and out of the chip, and requires alignment with submicrometer precision. Current methods are labor-intensive and time consuming and therefore unsuitable for large-scale production, or are unable to meet the alignment requirements altogether.
