Abstract

A method for making a highly birefringent optical fiber includes providing a preform with a substantially circular cross section. The preform includes a core region having a substantially circular cross section and a substantially elliptical cladding region adjacent the core region. The outer surface of the preform is modified to create a shaped preform with a non-circular cross section. The shaped preform is then drawn at a temperature and draw rate sufficient to provide an optical fiber with the non-circular cross section of the shaped preform.
