    摘要: A method for manufacturing an optical fiber includes the steps of covering an outer periphery of a first glass (11) having a first softening temperature and a non-axisymmetric structure by a second glass (12, 13) having a second softening temperature which is lower than the first softening temperature, heating the first and second glasses (11, 12, 13) for fusion together to thereby obtain an optical fiber preform; and drawing the preform to the optical fiber.
