  • Method of making optical fibers utilizing thermophoretic deposition of glass precursor particulates
    Patent number: 4263032
    Abstract: The deposition of glass precursor particulates, during optical fiber fabrication, is rendered more efficient by increasing the thermal forces which play a significant role in directing the particulate material to an appropriate substrate. Specific embodiments are addressed to various optical fiber fabrication processes, all of which involve the formation of glass particulate material and its subsequent deposition on an appropriate substrate.
