摘要：
In this manuscript, we have designed a circular photonic crystal fiber (PCF) having three rectangular holes filled with GaP in the core region, three air hole rings and one annular air ring in the cladding region. We found highest negative dispersion for the 1.8 mu m pitch along with very low confinement loss at wavelength 1.55 mu m. This designed PCF offers high nonlinearity (39,612 W-1 km(-1)) and high negative dispersion (- 6586 ps nm(-1) km(-1)) along with zero confinement loss at 1.55 mu m wavelength. We also compared the proposed PCF with the previously published PCF structure and found that the nonlinearity and negative dispersion of the designed PCF are very high in comparison to circular air hole based PCF. Other performance parameters viz. birefringence, numerical aperture, effective area, and effective material loss are also analyzed.
