Abstract
Square photonic crystal fibre (PCF) is proposed in this study using the principle of the golden ratio; by taking inspiration from nature. Simulations and analyses of the proposed design are used to examine different optical properties. Research findings show that the proposed square photonic crystal fibre exhibits a flattened chromatic dispersion, with a chromatic dispersion value of around 60 ps/(km.nm). At the critical 1.55 mm operating wavelength window, the fibre structure has a low effective area of less than 8 mm2 and confinement loss of less than 10−5 dB/km. These characteristics show that the proposed PCF design is suitable to be used for data communication systems. Subsequently, confinement of light occurs within the core of the proposed PCF at the optimum wavelength of 1.55 μm.
