Gorgi Kostovski and co-workers demonstrate on on p. 531 the parallel nanoimprinting of multiple optical-fiber facets on a novel imprinting platform. A passive, self-alignment mechanism is used to relax the mechanical demands placed on the imprinting platform, allowing the fiber array to accommodate the non-planarity of biological nanotemplates, as well as the demonstration of a compact, portable imprinting module. A resolution of better than 15 nm is demonstrated, and up to 40 optical-fiber facets have been imprinted in parallel. This demonstration will enable the high-throughput fabrication of fiber-facet devices in a high-resolution, cost-effective and accessible way.
