| Summary: | In this work, an extremely large mode area (LMA) photonic crystal fiber (PCF) design has been proposed having single mode operation. A full-vectorial finite element method (FEM) approach is considered with perfectly matched layer (PML) boundary for hybrid cladding with fluorine-doped silica holes in the cladding. An ultrahigh effective mode area can be achieved along with maintaining robust single mode operation. The hybrid cladding structure of the fiber makes it possible to exhibit lower bending loss and confinement loss. The proposed PCF design achieves an effective mode area of 1727.55μm2 at straight state and 719.08μm2 at bending state for a radius of 30cm at a wavelength of 1550nm. The proposed fiber also exhibits both an extremely low confinement loss of 4.745×10−4dB/Km and a bending loss of 6.11×10−4dB/Km at 30cm of bending radius at 1550nm wavelength. Moreover, the ultrahigh effective area of the fiber makes it possible to obtain an ultralower non-linear coefficient. |
