| Popis: | Fluoride preforms with single-mode geometry have been accomplished by drilling a small hole along the centre axis of an over-clad rod and inserting an Er 3+ -doped multimode preform stretched. From such preforms, single-mode fibres have been drawn, which could be used for the fabrication of optical amplifiers. Core–clad concentricity of the fibres depended on the precision of the drilling operation. Best fibres have a core non-circularity of 5.9%, a clad non-circularity of 3.3% and a core–clad concentricity of 1.7 μm. Fibre loss and bending strength were measured to be 0.48 dB/m and 0.83 GPa, respectively. |
