Latest Patents
Suto's latest patents include advanced fabrication methods for doped silica glass and optical fiber preforms. One notable patent describes a manufacturing method of doped silica glass suitable for optical fibers. This method involves exposing quartz powder or SiO₂ glass fine particles to a gas, which produces doped silica glass containing SiCl₄, a gaseous additive, and water vapor. The process allows for the addition of dopants to the glass body, which can be adjusted by changing the reaction time of dissolution. This innovation significantly increases manufacturing speed by separating the production of glass particles, the addition of dopants, and the vitrification of the glass body into distinct steps.
Another patent focuses on a core torch for fabricating single-mode optical fiber preforms. This invention allows for the production of fine glass particles eccentrically within a flame stream, facilitating the growth of a porous glass body on a seed rod. The resulting single-mode optical fiber exhibits a cladding-to-core-diameter ratio of three or more, enabling the mass production of long-length and low-loss optical fibers.
