したことを特徴とする偏波面保存光ファイバ。An optical waveguide is formed by surrounding the core with a cladding, surrounding it with an elliptical jacket containing a dopant having a larger coefficient of thermal expansion than the core and the cladding, and further surrounding the elliptical jacket with a dopant. In a polarization-maintaining optical fiber having a structure surrounded by a non-containing support, the elliptical jacket is divided into two layers to form an inner elliptical jacket layer and an outer elliptical jacket layer,
The thickness of the outer elliptical jacket layer is at most the same thickness as the inner elliptical jacket layer, and the dopant concentration of the outer elliptical jacket layer is higher than that of the inner elliptical jacket layer. Features polarization maintaining optical fiber.
