Abstract
A new simple structure of an index-guiding highly nonlinear dispersion-flattened square photonic crystal fiber (HNDFSPCF) with low confinement losses is proposed. The results reveal that it is possible to design five-rings HNDF-SPCFs with a flattened dispersion of 0.43 ps/(nm·km), low dispersion slope of -0:02 ps/(nm2·km), low confinement loss of approximately 103 dB/m, and a large nonlinear coefficient of approximately 35W-1 km-1 at 1.55 μm. It is also observed that the confinement loss is less than 10-1 dB/m in the wavelength range of 1.2 –1.7 μm.
