Nonlinearity and confinement loss of DC-PCF are evaluated by using a Full-Vectorial Finite Element Method (FV-FEM) successfully. By optimizing the geometry of three ring DC-PCFs, a high nonlinearity (52w-1km-1) and low confinement loss (0.001dB/km) can be achieved at 1.55μm wavelength when diameter to pitch ratio (d/Λ) is 0.70. %> http://ijop.ir/article-1-84-en.pdf %P 97-102 %& 97 %! %9 Research %L A-10-189-3 %+ Department of Applied Physics, Indian School of Mines, Dhanbad-826004, Jharkhand, India %G eng %@ 1735-8590 %[ 2011
