Latest Patents

Vergnano holds a patent for a "Process and apparatus for producing preforms for optical fibers." This patent describes a method where a vitrifiable substance, such as silicon chloride, and a doping agent, like germanium chloride, are combined in liquid form at room temperature. These materials are fed into a spray nozzle along with water or steam, allowing for continuous deposition on a cylindrical support. The process results in a heavy layer of unvitrified hydrated silica mixed with the doping agent, which is crucial for achieving a specific refractive-index profile. After degassing and potential separation from the support, the preform is treated with hot dehydrating gas to remove occluded water molecules. Finally, it is collapsed into a solid rod and vitrified at high temperatures.
