Latest Patents
Cavender's latest patents focus on enhancing the performance and manufacturing processes of optical waveguide fibers. The first patent is for an "Optical waveguide fiber with titania-silica outer cladding." This innovative fiber features a fatigue-resistant TiO2-SiO2 outer cladding that includes a cylindrical outermost layer with a TiO2 concentration exceeding 10.5 wt. % and a thickness of less than 3 µm. Additionally, the design allows for a two-layer outer cladding with a higher TiO2 concentration in the outer layer, along with a matrix containing dispersed inhomogeneities.
The second patent, titled "Method of manufacturing optical waveguide fiber with titania-silica," details a groundbreaking process for creating an optical waveguide fiber. This method involves depositing a glass soot TiO2-SiO2 outermost layer on a preform, exposing it to a chlorine atmosphere at high temperatures, and ensuring that the TiO2 concentration in the outermost layer decreases from its initial value. The fiber's outermost layer contains a significant volume percentage of crystalline phases, contributing to its unique properties.
