Abstract

In this paper, we report that it is possible to control chromatic dispersion of index guiding PCFs in wide wavelength range by arranging the major axis of the first inner ring perpendicular to that of the second inner ring. Using this unique arrangement, a newly PCF with ultra-low and ultra-flattened dispersion is designed through a finite difference method with anisotropic perfectly matched layers absorbing boundary condition. As an example, we have design a unique PCF with flattened dispersion of ±0.23 ps/(nm·km) from 1.5 to 1.8 μm wavelength and confinement losses of less than 10−13 dB/m in the wavelength range shorter than 1.8 μm.
