摘　　要：利用时域有限差分法(FDTD)设计了在1.15-1.35μm具有平坦色散的PBG光子晶体光纤,将光子晶体光纤的总色散分为波导色散和材料色散两部分分别计算,并利用包层空气孔间距Λ、包层空气孔径与空气孔间距的比值d/Λ及中心缺陷孔径与包层空气孔间距的比值r/Λ来改变波导色散。该光纤对于DWDM光纤通信系统具有重要意义。A Finite-Difference Time-Domain（FDTD） method is used to design photonic bandgap （PBG） fibers with flattened dispersion from 1150 nm to 1 350 nm. The dispersion of PBG fibers is obtained by the sum of material dispersion and waveguide dispersion, The relations between the dispersion and the structure parameters are discussed. It is found that the dispersion is closely connected with the Λ, and d/Λ. This kind of fiber has some potential applications in dense wavelength division multiplexing（DWDM） optical communication system.
