TL;DR: It is demonstrated that highly efficient evanescent-wave detection of fluorophore-labeled biomolecules in aqueous solutions positioned in the air holes of the microstructured part of a photonic crystal fiber even at wavelengths in the visible range is demonstrated.

TL;DR: In this article, a model for calculating the time necessary for filling one or more specific holes in a photonic crystal fiber is made, which is verified for water and its enabling potential is illustrated by a polymer application.

TL;DR: The fabricated photonic lantern has a coupling loss for a MM to SM tapered transition of only 0.32 dB which proves the feasibility of the technology and demonstrates efficient and reversible coupling between a MM fiber and a number of SM fibers.

TL;DR: A novel imaging fiber bundle ("hexabundle") that is suitable for low-light applications in astronomy and finds the important result that the cladding can be reduced to ~2 μm over the short fuse length, well below the conventional ~10λ thickness employed more generally.

TL;DR: Elect electrically and mechanically induced long period gratings in a photonic crystal fiber (PCF) filled with a high-index liquid crystal and a high polarization dependent loss of the induced gratings are observed.
