Slope matched highly birefringent hybrid dispersion compensating fiber over telecommunication bands with low confinement loss

Abstract

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 3.76×10 -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 -606 ps/ (nm.km) at 1550 nm effective wavelength. The reported fiber design matches the relative dispersion slope (RDS) 0.003694 nm -1 similar to single mode fiber at 1550 nm operating wavelength. This fiber demonstrates negatively flattened effective dispersion of -2.703 ± 0.734 ps/ (nm.km) within 180 nm flat band ranging from 1460-1640 nm wavelength. It is also convenient to optical high bit rate communication systems. The low confinement loss is found 3.756×10 -10 dB/m at the operating wavelength. This design also achieves highly nonlinear coefficient of 50.34 W -1 km -1 . In some cases, it can also be used in sensing applications.

“…Halder (2020) presents a slope-matched hybrid dispersion compensating fiber design with significant birefringence (3.76 × 10 −2 ) and an effective dispersion compensation range (1400-1625 nm), achieving a dispersion coefficient of −606 ps/(nm•km) at 1550 nm. This design showcases the potential for high bit-rate communication and sensing applications, along with low confinement loss (3.756 × 10 −10 dB/m) [14].…”

“…The fiber also showed outstanding dispersion compensation capabilities across all communication bands, with a negative dispersion coefficient of -378.6 ps/(nm.km) at 1550 nm and a relative dispersion slope similar to that of a single-mode fiber (Halder & Anower, 2019). Halder (2020) presented an optimized hybrid dispersion compensating fiber with high birefringence that covers the S, C, and L communication bands. The fiber has a negative dispersion of −606 ps/(nm•km) at 1550 nm, a relatively higher birefringence of 3.76× 10 -2 , low confinement loss, and a highly nonlinear coefficient of 50.34 W -1 km -1 , making it suitable for high-rate communication systems and potentially applicable in sensing applications (Halder, 2020).…”
