摘要： PROBLEM TO BE SOLVED: To provide a single-mode optical fiber in photonic crystal structure which is easy to manufacture and has the high degree of freedom of design of a dispersion characteristic and has a large core diameter. SOLUTION: The geometric diameter of a core part is made larger than twice as large as the mean interval between columnar holes by arranging two kinds of columnar holes which extend in the extending direction of an optical fiber and have different internal diameters in a clad part discretely at fixed intervals. Further, columnar holes which are arranged at an equal distance from the geometric center of the core part among the columnar holes arranged in the clad part are made equal in diameter. Those columnar holes are filled with a medium which is smaller in refractive index to light of wavelength guided in a vacuum or the fiber than the substance forming the fiber. Furthermore, the core part has a plurality of columnar holes extending in the extending direction of the fiber. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing an optical fiber capable of easily and simply being formed with a uniform thickness of coating in a circular direction without controlling the thickness of coating during heat drawing the optical fiber having a plurality of fine through holes extending in an axial direction of the fiber. SOLUTION: A optical fiber preform 1 is formed by jointing while aligning an axis of a 1st preform 31 having a plurality of through holes extending along the axial direction with an axis of a 2nd solid preform of almost same diameter. The optical fiber 2 is manufactured by heating and drawing the fiber preform 1 from a side of the 2nd preform 32. The optical fiber 2 is coated with resin by a die, wherein the thickness of coating is measured and the position of the die is adjusted so as to obtain the nearly uniform thickness of coating in the circular direction. If the thickness of coating is made nearly uniform while heat drawing the 2nd preform 32, the optical fiber 2 drawn from the 1st preform 31 is coated with nearly uniform thickness without measurement or adjustment for the 1st preform 31 part.
