摘要：

In this paper, we propose and demonstrate a novel type of PCF that has two cladding layers with Ge rods at the center core. We numerically show that it is possible to design a single mode PCF with large effective area greater than 200 mu m(2) over the whole wavelength above 1.2 mu m. The proposed large mode area PCF (LMA-PCF) exhibits a high negative dispersion coefficient from -186 to -158 [ps/(nm-km)] in all wavelengths ranging from 1.2,mu m to 1.8 mu m. Effective single mode operation of LMA-PCF is confimed for the entire band of interest.
