Photonic Crystal Fiber And Tunable Pulse Produced By Research

In1992, St. J. Russell, who proposed the new concept of the photonic crystal fiber, making the lead in the worldwide in-depth study of the photonic crystal fiber theory and practical application of the boom. The introduction of the photonic crystal structure of production to new fiber, called photonic crystal fiber in the fiber. It has the ordinary fiber has superior optical properties, which makes it has a wide range of applications,In this thesis, the use of the Rsoft simulation software simulation of photonic crystal fiber light guide characteristics and structural parameters of the relationship between, and instructive.In the light in the crystal concept leads to a photonic crystal fiber, described the fine features of the photonic crystal fiber and two types of photonic crystal fiber light guide principle, characteristics and applications. Elaborate analysis, the choice of plane wave expansion method, the simulation analysis of PBG-PCF, the TIR-PCF band structure, and analyze the light in which the propagation characteristics and design on this basis to increase the effective mode area photonic crystal fiber, it has an excellent "single mode" feature.Simulation of optical solitons in photonic crystal fibers, photonic crystal fiber transmission, base band and the high-end optical solitons and analyze the interaction between the soliton to discuss the impact of third-order dispersion on the high order soliton interaction self-steepening and self-frequency shift effect of second-order soliton transmission. Stimulated discussion on the third-order dispersion, self-frequency shift effect and second-order soliton transmission, the use of numerical simulation to discuss the mechanism of the optical soliton tunable pulsed.
