摘要
Using a full-vector finite-difference time-domain （FDTD） method, this article explores the propagation characteristics of photonic crystal fiber （PCF） theoretically. The dependence of structural parameters on the effective index of the fundamental guided mode, effective index of the fundamental cladding mode, mode field diameter, confinement loss, effective mode area, and chromatic dispersion in PCF have been studied, respectively. The research presents a reference for designing of PCF with a specific purpose.
