Theoretical Treatment to Determine the Quality of Photonic Crystal Fiber (PCF) as a Function of the Number of Air Holes

Abstract

In this paper, the design of photonic crystal fiber (PCF) depending on the number of holes and rings is presented. Three different types of PCF will be assumed. The effect of increasing number of holes was explained using the relations between chromatic dispersion (Dc), loss, bit error rate (BER) and pitch (ᴧ) for wavelength interval 1-2µm and three fiber lengths (50, 100 and 200 km). These relations were plotted using MATLAB-2008 software. The obtained results showed that the 3rd PCF with the highest number of holes has provided better quality than the other two types of PCF.
