Summary: | : The present invention relates to a method of producing a preform for a single-polarisation optical fiber being elliptical in cross section. The method is comprised of the steps of forming a thin glass film to become a cladding layer, or a jacket layer or thin glass films to a cladding and jacket layers on the inner wall of a glass mother tube. The method includes the step of inserting a glass rod to become a core or a cladding into the mother tube and the step of heating the mother tube while at the same time providing a reduced pressure within the mother tube so that the whole arrangement becomes a solid preform. |
