    摘要: Disclosed is a process for producing a holey fiber preform through a sol-gel molding method. The process comprises the steps of: (a) expanding a plurality of elongated tubes, wherein the tubes can be expanded/contracted by control of pressure in the tubes, (b) positioning the expanded tubes in the mold in a predetermined arrangement; (c) introducing a sol gel into the mold; (d) separating the gel from the mold, and contracting the tubes to form elongated air holes in the gel; and (e) removing the tubes. In the process, the tubes for forming air holes can be removed with no impact on the dried gel.
