Applications of Selectively Filled Photonic Crystal Fibers — •Marius Vieweg, Timo Gissibl, and Harald Giessen — 4th Physics Institute, University of Stuttgart, Pfaffenwaldring 57, 70569 Stuttgart, Germany

Filling the holes of a photonic crystal fiber with different media has gained a lot of interest in the recent past for several different optical applications. With our method we are now able to close and fill the fibers selectively with different liquids. There are numerous possible applications for this new optical device. As two examples we present first a single-strand structure embedded in a standard photonic crystal fiber. Here we could measure spectral broadening due to self-phase modulation. As a second example we present a more complex structure. Several single holes infiltrated with a liquid form a liquid waveguide array, in which the waveguides are separated from each other by unfilled holes. We present here the linear propagation as well as coupling effects. For further applications it is possible to tailor the dispersion properties, the nonlinearity, as well as the spatial arrangement of the waveguides for nonlinear light propagation in two-dimensional discrete optical systems.
