Abstract

There is interest in photonic crystal fibers (PCFs) that possess a large effective area. We demonstrate that it is possible to design a PCF structure configuration with an effective mode area as high as 3000 $\mu$m$^{2}$. The proposed PCF structures consist of five air-hole rings, where the air hole diameters are different from one ring to another. In the second ring six air holes are alternatively removed. The effective mode area of the proposed structure was calculated and compared with effective mode areas reported in literature. It is shown that the effective mode area is enhanced compared to other structures. Additionally, critical propagation properties such as chromatic dispersion, confinement losses, bend losses and nonlinear coefficient of proposed PCF structures are reported thoroughly.
