Subwavelength-diameter silica wires for low-loss optical waveguiding
TLDR
In this article, a two-step process is described to generate a micrometer sized diameter silica preform fiber, and then the preform is drawn while coupled to a support element to form a nanometer sized diameter fiber.Abstract:
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 utilizes a two-step process in which in an initial step a micrometer sized diameter silica preform fiber is generated, and in a second step, the silica preform is drawn while coupled to a support element to form a nanometer sized diameter silica fiber. The portion of the support element to which the preform is coupled is maintained at a temperature suitable for drawing the nansized fiber, and is preferably controlled to exhibit a temporally stable temperature profile.read more
