摘要：

We propose a novel design for all-solid photonic bandgap fiber (AS-PBGF) by introducing defect rods with larger diameters into fiber cladding. By means of the plane-wave expansion method and the full-vector finite-element method, we study the effect of introducing such defect rods and numerically investigate dispersion characteristics of proposed AS-PBGF. Simulation results demonstrate that large wave guide group-velocity dispersion (GVD) (both normal and anomalous) is induced within bandgap rather than near the edge of bandgap as conventional photonics bandgap fiber does, which guarantees that large dispersion and low confinement loss could be simultaneously achieved. We also find that there are two essential factors affecting the slope of wave-guide GVD, which determines the third-order dispersion: number of defect rods and the ring where defect rods are introduced.
