偏波面保存光フアイバ。 In a polarization-maintaining optical fiber having a structure in which a jacket that applies stress to the core is arranged at a symmetrical position with respect to the core center, and a cladding is arranged outside the core and the jacket, the refractive index of the core is the same as the jacket. The polarized refractive index is equal to or higher than the jacket so that the relative refractive index difference is within -0.05%, and the spacing between the core and the jacket is set to three times the core radius or less. Wavefront preserving optical fiber.
