| 摘要 |
An optical waveguide has a silica cladding and a phosphosilicate core. Additional components may be added to improve the match of physical properties between core and cladding. The waveguide is manufactured by passing a mixture of vapors of silicon tetrachloride and phosphorus oxychloride through the interior surface of a glass tube and heating to cause oxidation and simultaneous deposition of silica and phosphorus pentoxide. The interior coated tube is then collapsed to a rod and the rod is drawn into an optical fibre. |
