He holds 2 patents that showcase his innovative approach to manufacturing high-purity glass tubes and optical fiber preforms. His work has significantly impacted the development of optical fibers, which are essential for modern communication systems.

Latest Patents

One of McDonald's latest patents involves the manufacture of high-purity glass tubes. This process includes applying a first soot on an end face of a starting member to create an elongated, porous cylindrical soot core. A second soot, which includes SiO, is then applied to the periphery of the soot core to form a porous soot cladding. The core and cladding are heated together to form core glass and cladding glass. Due to the differing rates of collapse during sintering, the core glass separates from the cladding glass, resulting in a high-purity glass tube suitable for optical fiber preforms. Another significant patent focuses on the manufacture of optical fiber preforms using a modified VAD process. This method dynamically controls the reaction temperature at the tip of a soot preform by regulating the flow of hydrogen gas, allowing for a uniform composition of the preform.
