Abstract

This paper presents a novel non-defective core photonic crystal fiber (PCF) which was found to produce three zero dispersion wavelength (ZDW), which may lead to a very powerful spectral densities compared to that of single or double ZDW PCFs. More so, the presented PCF design not only has the three ZDW achieved for the PCF, but also, been able to achieve a high negative chromatic dispersion (−220.39 ps/km.nm), and ultra-flatted chromatic dispersion of ± 0.9 ps/km·nm within operating wavelength range of 1.53–1.8 μm. These characteristics may be helpful for applications in the fields of supercontinuum generation (SCG), soliton pulse transmission, and detecting or sensing and optical communication systems. The propagation properties of the proposed PCFs: effective index, confinement loss and chromatic dispersion, are well researched making use of full vectorial finite element method (FEM).
