Simple splicing and reduced coupling losses when joining optical solid- and hollow-core fibers

Optical fibers are particularly well suited for long-distance data transmission, as the attenuation losses are significantly lower than e.g. when using copper conductors. Scientists at the University of Stuttgart have now developed a simple and flexible method of joining solid- and hollow-core fibers that is characterized by low coupling losses and easy and flexible handling. In particular, it is suitable for liquid-filled hollow-core fibers. The method enables a durable, low-loss connection of fibers of different diameters without the application of heat required.
