(Phys.org) -- A simple longitudinal twist converts certain microstructured optical fibres into filters. Researchers at the Max Planck Institute for the Science of Light in Erlangen have measured this effect in detail in photonic crystal fibres and found a theory to explain it. The results of their research will allow new applications in optical communications and the construction of lasers, sensors and light amplifiers.
