Abstract :
In this paper, we propose and demonstrate a novel type of PCF that has two cladding layers with Ge rods at the center core. The authors numerically show that it is possible to design a single mode PCF with large effective area greater than 200 mum over the whole wavelength above 1.2 mum. The proposed LMA-PCF exhibits a large negative dispersion coefficient from -186 [ps/nm-km] to -158 [ps/nm-km] in all wavelengths ranging from 1.2 mum to 1.8 mum, mainly for applications as dispersion compensating in wideband high speed optical transmission systems.
