Paper Abstract

We report about spectral transmission behavior and influence on chromatic dispersion of index guiding microstructured fibers (MOFs) in terms of material effects of the light propagating core, geometric parameters of the microstructured cladding and preparation parameters. Two core compositions were investigated pure silica and silica-germania glass with maximum 36 mol% GeO2. The MOFs with large pitch (>5 μm) were manufactured by single step technique. Small pitch MOFs were prepared by dual step method. They show a relatively high OH absorption. The dual step prepared silicagermania MOFs show a more than one order of magnitude higher hydroxide contamination compared to similar silica MOFs. This result seems to be caused by the higher permeation of hydroxide groups in silica-germania glass compared to silica. Simulations show that the red shift of the zero dispersion wavelength (ZDW) caused by high germanium doping can be compensated by a holey cladding structure with medium up to large ratios of d/Λ.
