Abstract: The present invention relates to a glass article for use as an optical waveguide fiber (1), the core (4) of which is doped with a chalcogenide element to significantly increase the refractive index of the core (4). The subject of this invention is novel doped silica core composition wherein a portion of the oxygen in the silica is replaced with either sulfur, selenium or tellurium using plasma enhanced chemical vapor deposition (PECVD). These compositions are designed to have higher refractive indices than silica, low coefficient of expansion, high optical transparency and appropriate viscosity and softening points to make them ideal candidates for use as optical waveguide fibers.

Abstract translation: 本发明涉及一种用作光波导纤维（1）的玻璃制品，其核心（4）掺杂有硫族化物元素以显着提高芯体（4）的折射率。 本发明的主题是新型掺杂二氧化硅芯组合物，其中使用等离子体增强化学气相沉积（PECVD）将二氧化硅中的氧的一部分用硫，硒或碲代替。 这些组合物被设计为具有比二氧化硅更高的折射率，低的膨胀系数，高的光学透明度和适当的粘度和软化点，使其成为用作光波导纤维的理想候选物。
