摘要
In this paper, we propose an air-silica based octagonal photonic crystal fiber (O-PCF) of ultra-high negative dispersion of -1755 ps/(nm.km) and large nonlinearity of 104.1 W(-1)km(-1) is proposed. Ultra-high negative dispersion is achieved by introducing small air holes of different sizes in the fiber geometry. For the investigation of the dispersion features and non-linearity of the suggested PCF, the Finite Element Method (FEM) was implemented. In addition, +/- 2% deviation in optical characteristics is evaluated and reported in order to study the practical feasibility of the proposed O-PCF. The large negative dispersion and high nonlinearity of our proposed design make it a strong candidate for optical broadband communication, super continuum generation, and sensing.
