The surfaces of 411-impregnated S-cathodes have been investigated by SFM/STM (= scanning force microscopy and scanning tunnelling microscopy) and SEM/EDX. The S-cathodes of different origin consist of a tungsten matrix (20% porosity) and are impregna

The stress properties of GeO(2)- and F-doped optical fibers drawn in different conditions have been investigated. The results are in excellent agreement with calculated data based on a generalized theoretical model. For constant drawing forces the in

The intrinsic stress properties of GeO2- and F-doped optical fiber preforms have been investigated in detail. The materials were prepared by low-pressure plasma-induced chemical vapor deposition (PCVD), and the dopant concentrations cover the range n

The influence of drawing induced stress on the light-guiding properties of dispersion-flattened single-mode (DFSM) fibers has been investigated. The measured differences of the refractive index profiles of fibers drawn with different drawing forces c
