Abstract—An octagonal 5-layer air-hole dispersion compensating photonic crystal fibre is presented in this paper. The design is based on the golden ratio principle where the pitch to air hole diameter ratio is kept at 1.618. Numerical analysis using full-vector Finite Element Method (FEM) with a perfectly matched layer boundary CONDITION is used to investigate optical properties of the Photonic Crystal Fibre (PCF). At its optimum pitch value, high negative dispersion of 295 ps/(nm.km) and low confinement loss of 0.00755 dB/km is achieved at 1550 nm wavelength. Similarly, the proposed PCF also yields negative dispersion and low confinement loss on the E+S+C+L+U wavelength bands and partially on the O band with optimum pitch. These properties point to the suitability of the proposed PCF for potential application as a dispersion compensating fibre.
