摘要: An optical waveguide including a core, a buffer surrounding the core, and a cladding surrounding the buffer. The core, the buffer and the cladding include silica glass. A refractive index of the buffer is substantially equal to a refractive index of pure amorphous silica glass. The buffer may reduce bubble formation during manufacturing and may facilitate splicing of the waveguide. A numerical aperture of the waveguide may be fine-tuned by adjusting a radial dimension of the buffer in order to compensate variations in the refractive index of the core.

摘要: A method and manufacturing apparatus for forming one or several material layers inside a basic tube, which basic tube is used in the manufacture of an optical fiber preform. The surface inside the basic tube is electrically charged by guiding a first electrically charged gas flow inside the basic tube, whereafter a second electrically charged gas flow is guided into the basic tube. The gas flow contains material particles and the sequentially alternating first gas flow and second gas flow have opposite charges.
