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. |
