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

Madhavi Harish Waghmare, K.T.V. Reddy


This paper investigates 4 new different structures of Photonic Crystal Fiber (PCF) for broadband application 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 range from 163.55 THz to 259.11 THz i.e. 1.157 µm to 1.833 µm with a dispersion in the range of -250 ps/nm/km till -700 ps/nm/km. The results obtained from the new different PCF structures are compared with earlier results for different 2D PCF models so far.
