Photonic crystal fiber preform and photonic crystal fiber manufactured using the same

摘要

The preform (100) has a rod-shaped substrate (110) with holes longitudinally formed in a photonic lattice structure. Materials are disposed in the holes of the rod-shaped substrate and have different indices of refraction (120,130,140). The distribution of refraction index of the preform is controlled by arrangement of the materials. Each material is formed in the shape of a rod. An independent claim is also included for a photonic crystal fiber.
