The present invention provides nanometer-sized diameter silica fibers that exhibit high diameter uniformity and surface smoothness. The silica fibers can have diameters in a range of a about 20 nm to about 1000 nm. An exemplary method according to one embodiment of the invention for generating such fibers...http://www.google.com/patents/US7620281?utm_source=gb-gplus-sharePatent US7620281 - Subwavelength-diameter silica wires for low-loss optical waveguiding
