Abstract
Disclosed is an apparatus for fabricating a preform used to manufacture a photonic crystal optical fiber having multiple holes extending in a longitudinal direction thereof. The apparatus includes a housing for containing a raw material for the photonic crystal optical fiber; a first support member positioned at one end of the housing; a second support member positioned at the other end of the housing; and multiple tubes respectively supported by the first and second support members to be at least partly located within the housing, wherein diameter of each multiple tube can be variable selectively depending on an amount of fluid poured through the open ends of the tubes.

An apparatus for fabricating a preform used to produce a photonic crystal optical fiber having multiple holes extending in a longitudinal direction thereof, comprising:
- a housing for housing a raw material used to produce the photonic crystal optical fiber;
- a first support member disposed at a substantially horizontal orientation at one end of the housing;
- a second support member disposed at a substantially horizontal orientation at the other end of the housing;
- and
- a plurality of multiple tubes supported by the first and second support members to be at least partly located within the housing, wherein each of the multiple tubes has one open end and the portions of the tubes located within the housing are variable in diameter depending on a pressure of fluid poured through the open ends of the tubes.
A method for fabricating a preform used to produce a photonic crystal optical fiber having multiple holes extending in a longitudinal direction thereof, the method comprising the steps of:
- providing a plurality of expandable tubes in a substantially vertical orientation in a housing;
- selectively pouring a fluid into the expandable tubes to expand each tube to a predetermined diameter;
- providing a sol into the housing and performing a gelling process of the sol;
- removing the fluid from the expandable tubes;
- and
- removing the housing to release the gel.
