Abstract: PURPOSE: A polarization-maintaining optical fiber and a manufacturing method for the same are provided to use the cladding region by doping heterogeneous materials onto an optical fiber to form a silica layer. CONSTITUTION: An outer layer of a core is provided with a silica layer onto which heterogeneous materials whose thermal expansion coefficient and refractive index are reciprocal are doped. The heterogeneous materials are phosphorus and fluorine. An asymmetric induced residual stress generating region is formed by cutting both ends of a base material. A silica layer for use in a cladding region is formed on the both sides of the base material. Then, the base material is drawn with a desired strength. The base material is coated with a polymer.
