Design and Modal Analysis of Photonic Crystal Fiber for Dispersion Compensation over Broadband Range

Abstract In this paper we have presented the four new investigations using different structures of Photonic Crystal Fiber (PCF) for broadband communication applications and narrows down on the design which can provide largest flat negative dispersion. The new structure model is optimized based on the combination of modal properties and dispersion compensation. The results were recorded over a transmission frequency range from 190.95 THz to 245.73 THz i.e. 1.22 µm to 1.57 µm with a dispersion −704.62 ps/nm/km. The results obtained from the new different PCF structures are compared with reported results for different 2D PCF models so far
