The lowest loss optical waveguides to date are those of high silica composition prepared by vapor deposition. The present article describes a method for producing waveguides having a GeO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> -SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> core and SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> cladding. These combine low loss with relatively large index differences between core and cladding, Large index differences create problems in optical communication systems because of dispersion effects. Means of index grading so as to decrease dispersion are also described.
