Latest Patents

Among his latest patents, the "Method of Silica Optical Fiber Preform Production" stands out prominently. This invention introduces a novel method for manufacturing optical fiber preforms using plasma enhanced chemical vapor deposition (PECVD). The process involves a cylindrical reactor where materials, such as fluorine-doped silica glass, are deposited onto a cylindrical silica rod. A furnace envelops the reactor, ensuring precise temperature regulation. By employing a microwave generator linked with a resonator and an H-waveguide, microwave energy is delivered to the reactor, enabling symmetrical excitations in the E-mode and a plasma surface wave at the rod's surface. This technique not only enhances power absorption but also enables uniform deposition of films on rods with diameters ranging from 30 to 35 mm, ultimately leading to the production of optical fiber preforms exceeding 40 mm in diameter.

Another significant patent is the "Method for Production of Silica Optical Fiber Preforms." This document describes a device and method employing microwave plasma-assisted chemical vapor deposition for the fabrication of optical fiber preforms. The process initiates with the introduction of precursor gas to a vertically oriented dielectric rod, where a plasma is generated through simultaneous excitation of E-type and H-type waves with rotating linear polarization. The arrangement enables the precise delivery of microwave energy, facilitating the deposition of both a pure or doped core alongside a doped cladding.
