Abstract
In order to study effect of the silica ring at the core-cladding interface on the transmission bandwidth, dispersion,core-confined energy and nonlinear coefficient, for the designed 7-cell hollow-core photonic bandgap fibers (HC-PBGFs), they were numerically simulated by means of full-vector finite element method, and the curves of the transmission bandwidth,dispersion, core-confined energy, nonlinear coefficient in different normalized thickness of the silica ring with the same core radius were obtained.The simulation results show that the best range of normalized thickness of silica ring is 0.5 to 0.6, which provides theoretical evidence to design the HC-PBGFs.关键词
