Fabrication method and device for porous optical fiber preform |
摘要 |
Disclosed are fabrication method and device for a porous optical fiber preform. The fabrication method includes the steps of (a) rotating one or more rotating disks in a deposition furnace, wherein a plurality of shoot rods are coupled to the one or more rotating disks and spaced at predetermined intervals along a circumferential direction of the one or more rotating disks; (b) supplying a raw material in a gaseous state into the deposition furnace to deposit the raw material onto the shoot rods; (c) after the formation of a silica shoot by deposition of the raw material on the shoot rods, eliminating the shoot rods from silica shoot; and (d) sintering the silica shoot from which the shoot rods are eliminated.
