METHOD OF MANUFACTURE OF BLANKS REPROCESSING OF FIBER LIGHT GUIDES ON THE BASIS OF A QUARTZ GLASS Russian patent published in 2005 - IPC

FIELD: fiber-optic communication; medicine; opto-and- microelectronics; methods of production of quartz blanks of the fiber light guides.

SUBSTANCE: the invention is pertaining to the methods of production of quartz blanks of fiber light guides by a deposition from a gas phase and may be used in various systems of a fiber-optic communication, medicine, opto-and- microelectronics. The method is based on a deposition of layers of a shell and a core on an exterior surface of a support quartz pipe made out of engineering quartz glass, which in the further is etched out in the process of a collapse into a stud-plank in the result of passing through it of a mixture of the chemically reactive gases (for example, SF₆) with oxygen. At that the support quartz pipe is tightly set on a metal pipe forming a metal-dielectric wave-guiding structure necessary for excitation and propagation along it of an UHF-discharge on a surface wave. Relocation of the front of the UHF-discharge is carried out by modulation of the fed to the metal-dielectric wave-guiding structure of the UHF-power. The method ensures a capability of shaping of blanks of the light guides practically of any types and compositions, and also allows to refuse the high-quality and high-expensive quartz pipes, to reduce the prime cost of the produced blanks, to increase the factory length of the light guides due to an increase of diameter of molded blank.

EFFECT: the invention allows to shape the light guides blanks of any types and compositions, to refuse the high-quality and high-expensive quartz pipes, to reduce the prime cost of the produced blanks, to increase their factory length.
