The MPL Technology Development and Service Unit: Fibre Fabrication & Glass Studio Researchers at the Max Planck Institute for the Science of Light and the Universitat Politècnica de València (UPV) use specially developed fibers to control the timing of signals propagating at the speed of light precisely. This image shows the preform of a glass fiber, which was created by manually stacking many glass rods. The glass fiber consists of 19 fiber cores with various refractive index profiles. Some have high indices in their centers, which decrease radially towards the edges before undergoing a step change to either a lower or a higher index. Other cores have a high index in the center and two steps with progressively lower indices. Each fiber core therefore has its own dispersion spectrum, as a result of which optical signals in the 19 cores propagate with specific time delays. © 📸: Linda Uta

1moIf nothing else the fiber preform at least looks beautiful! But it could have some very interesting applications, especially if combined with a fast switch to control which core the signals get routed to.
