3-D nanoprinting facilitates communication with light
(PHYSorg.com Physics)

At Karlsruhe Institute of Technology (KIT), researchers have developed a flexible and efficient concept to combine optical components in compact systems. They use a high-resolution 3-D printing process to produce tiny beam-shaping elements directly on optical microchips or fibers and, hence, enable low-loss coupling. This approach replaces complicated positioning processes that represent a high obstacle to many applications today. The scientists present their concept in Nature Photonics.
