Abstract

The stack and draw technique provides an enormous flexibility and permits to obtain rather complex photonic crystal fibers and other nanoweb structures. It is possible to fabricate Ge-doped microstructured fibers combining silica capillaries and doped wires of silica glass. Here, we will present the fabrication and postprocessing of Ge-doped Y-shaped fibers. These structures may exhibit strong evanescent fields in the air holes, while the presence of a Ge-doped core increases the versatility when designing new fiber-optic components.
