Paper Abstract

We propose a novel design for photonic crystal fiber, which has flattened-dispersion, high nonlinear coefficient and low confinement loss for supercontinuum generation. The proposed fiber needs appropriate number of design parameters. Results show that eight-ringed photonic crystal fiber is obtained with nonlinear coefficient greater than 33W-1 km-1, and small dispersion slope 2.00×10-3ps/nm2/km in the telecommunication window. Ultra flattened dispersion of -1.65~ 0.00 ps/nm/km and confinement loss in super low order of 10-4dB/km are simultaneously obtained ranging from 1.45μm to 1.65μm. It's shown that through numerical analysis the novel micro-structured optical fiber with small normal group-velocity dispersion and nearly zero dispersion slope offers the possibility of efficient supercontinuum generation in the telecommunication window using a few ps pulse. supercontinuum with 70nm-bandwidth at 1550nm is achieved through only 150m-long fiber.
