Ultra-flattened chromatic dispersion photonic crystal fiber with high nonlinearity for supercontinuum generation

We propose a novel design for photonic crystal fiber, which has flattened-dispersion (between −1.65 and 0.0 ps/nm/km from 1.45 to 1.65µm), high nonlinearity (larger than 33 W

) and low confinement loss (order of 10
⁻⁴
dB/km). Analysis shows flat supercontinuum (70nm) at 1550nm is achieved through only 150m-long fiber.
