Highly nonlinear and highly birefringent dispersion compensating photonic crystal fiber

Dispersion compensation in optical transmission systems using high negative dispersion chalcogenide/silica hybrid microstructured optical fiber

“…To investigate the possibility of dispersion compensation in a wide range of wavelengths, the relative dispersion slope (RDS) is used. RDS is calculated in nm −1 using the following equation [1][2][3][4]31]:…”

A new circular chalcogenide/silica hybrid microstructured optical fiber with high negative dispersion for the purpose of dispersion compensation

“…Some of the DCFs proposed in recent years that are based upon MOFs for compensating dispersion are mentioned below. The MHF proposed in [1] has a dispersion coefficient value of -1455 ps/(nm km) at 1.55 µm, the novel pure silica DC-MOFs proposed in [2] has a dispersion coefficient of about -130 to -360 ps/(nm km) at 1.4 -1.6 µm, and the broadband DC-HyPCF proposed in [3] has a dispersion coefficient of about -555.93 ps/(nm km) at 1.55 µm. The dispersion coefficient in the proposed M-OPCF in [4] is about -588 ps/(nm km) at 1.55 µm and the C-PCF proposed in [6] has a negative dispersion of about -248.65 to -1069 ps/(nm.km) over E to L wavelengths.…”

“…In fiber-optic communication systems, dispersion in transmission fibers limits both the data bit rate and the data transmission distance [1][2][3][4]. Dispersion causes the widening of the optical signals when propagating through an optical fiber.…”

Design of single-polarization single-mode coupler based on dual-core photonic crystal fiber

“…[1][2][3][4][5] The flexible control of air hole allows the construction of complex dualcore or multicore structures. 6,7 Couplers, which can guide light power to other optical components in appropriate proportions, are essential for all-fiber systems and have been extensively applied in optical fiber sensing systems and coherent optical communication systems.…”
