This article reveals a best possible design for hybrid dispersion compensating fiber (HyDCF) with high birefringence established on modified broadband compensating structure through S, C and L telecommunication bands. The simulation outcome exhibits relatively higher birefringence of 3.193×10-2 at wavelength of 1550 nm. The suggested fiber also has dispersion compensation characteristics in an inclusive series of wavelengths which covers 1400-1625 nm. The reported design can achieve dispersion quantity of – 343.57 ps/ (nm.km) at 1550 nm effective wavelength. The reported fiber design matches the relative dispersion slope (RDS) 0.003561 nm-1 similar to single mode fiber at 1550 nm operating wavelength. This fiber demonstrates nearly zero flatten effective dispersion of – 1.1706 ± 0.6425 ps/ (nm.km) within 250 nm flat band ranging from 1450-1700 nm wavelength. It is also convenient to optical high bit rate communication systems. The low confinement loss is found 1.525×10-9 dB/m at the operating wavelength. This design also achieves highly nonlinear coefficient of 40.33 W-1km-1. In some cases, it can also be used in sensing applications.
