The simulation results showed that high birefringence of 3.039 × 10⁻² was obtained with a high nonlinear coefficient of 33.76 W⁻¹ km⁻¹ at an effective wavelength of 1550 nm. The fiber also exhibited dispersion compensation properties over a broad range of wavelengths covering the S to L communication bands. The proposed design achieved a negative dispersion coefficient of −378.6 ps/(nm-km) at an effective wavelength of 1550 nm. This fiber also had a relative dispersion slope of 0.003623 nm⁻¹ at an operating wavelength of 1550 nm, which is very close to that of a single mode fiber. This Hy-PCF is suitable for high bit rate communication systems because it allows single mode operation, as well as for optical sensing applications due its high birefringent property.en© 2019 Elsevier B.V.
