METHOD TO MANUFACTURE QUARTZ STOCKS OF SINGLE-MODE FIBRE WAVEGUIDES, DEVICE FOR ITS REALISATION AND STOCKS MANUFACTURED BY THIS METHOD Russian patent published in 2011 - IPC C03B37/18 

FIELD: technological processes.

SUBSTANCE: invention relates to manufacturing of quartz stocks of single-mode fibre waveguides for fibre-optic lines of communication, development of fibre lasers and amplifiers, various fibre-optic sensors. Only a core of a stock is deposited by gas phase deposition in SHF plasma of lower pressure to the inner surface of a thick-wall quartz or fluorosilicate support pipe with wall thickness of 8-10 and more mm. Deposition is carried out in SHF plasma of lower pressure in the range of 1-30 torr, developed by combined SHF plasmotron of resonator type on type of oscillations TM₀₁₀ and TE₁₁₁ with simultaneous combination of resonance frequencies, but with various distribution of electromagnetic fields. SHF plasmotron is an SHF resonator device on the type of oscillations TM₀₁₀ and TE₁₁₁ with simultaneous combination of resonance frequencies, but various distribution of electromagnetic fields.

EFFECT: increased efficiency of single-mode fibre waveguide stocks manufacturing process and general reduction of cost to produce quartz single-mode fibre waveguides.
