We present a Raman based investigation focused on the comparison of the Boson peak in pure and Ge-doped core optical fibers. In addition to the composition effects, we investigated the drawing effects and the γ-ray effects on this Boson peak. Our data indicate that the spectral features of the boson peak are not affected by varying the drawing tension and speed within the ranges used for the production of specialty fibers, by Ge doping level up to 9 wt% and by gamma-rays up to 8 MGy dose.
