    摘要： A photonic crystal fiber (PCF) preform, from which a photonic crystal fiber is manufactured, includes a rod-shaped substrate with holes longitudinally formed therethrough in a photonic lattice structure, and material layers having at least two different indices of refraction. The material layers are disposed in the holes, respectively. Distribution of index of refraction of the photonic crystal fiber preform is controlled by arrangement of the material layers. Consequently, an optical fiber with very low optical loss, very low optical nonlinearity and excellent transmission characteristics can be easily manufactured, and an optical fiber with various characteristics, differing depending upon the lattice structure, can be realized.

    摘要： A photonic crystal fiber capable of single-mode transmission and a preform thereof are disclosed. The photonic crystal fiber includes a substrate and a plurality of refraction index-adjusting material layers, each having a different refraction index, wherein the refraction index distribution of the fiber is the same as an electric field power distribution of incident light to be transmitted through the fiber. The photonic crystal fiber can minimize pulse dispersion caused by light loss and refraction-index deviation due to the incident light passing through a zone away from an actual core.
