The optical fiber communication technology is a subject to be concerned, and photonic crystal fiber (PCF) is thought to be one of the most promising technologies in this field. Micro structured polymer optical fiber (MPOF) may put in the first place in the media for final 100 m~1000 m optical fiber communication systems because of inherent the merits of both polymer optical fiber (POF) and PCF. So far, there are two classes of hollow-core fibers and they are Bragg fiber and photonic bandgap fiber. They all confine light in their hollow core through photonic bandgap effect. Our research group proposed a cobweb cladding structure hollow-core fiber after taking into account all aspects of the above two classes of hollow-core fiber. It can be fabricated with only one material and have much more advantages.Based on the study of a great number of references, firstly, the actualities and principle of the PCF is introduced and the difference between the cobweb-cladding structured fiber and the existent fibers is analyzed. Secondly, the Asymptotic Transfer Matrix Method is particularly recommended, including the principle, formulas, numerical method and boundary condition. Finally, by using the Asymptotic Transfer Matrix Method, we thoroughly analyze the performance and the effect of the various structural parameters for the cobweb-structured cladding fiber different applications, such as visible light, infrared, terahertz wave and so on. It is proved that the cobweb-structured cladding fibers have a lot of excellent performance on the different application.
