We present a new cladding design for photonic crystal fiber (PCF) on a decagonal structure to simultaneously achieve ultra-flattened large negative dispersion and ultrahigh birefringence. Numerical results confirm that the proposed PCFexhibits ultra-flattened large negative dispersion over the S + C + L + U wavelength bands and average dispersion of about −558.96 ps∕nm∕km with absolute dispersion variation of 9.7 ps∕nm∕km from 1460 to 1675 nm (215 nm bandwidth). Moreover, ultrahigh birefringence of 0.0299 is also achieved at a 1500 nm wavelength. © 2015 Optical Society of America
