C-band high nonlinear optical fiber dispersion 0.0±1ps/(nm.km

Nonlinear effects in optical fibers, such as stimulated Raman scattering (SRS), stimulated Brillouin scattering (SBS), and the optical Kerr effect, have many applications in the fields of communications and optical signal processing. In the Kerr effect, the refractive index of the light-guiding medium changes with the optical power, which will lead to a series of secondary effects, such as self-phase modulation (SPM), cross-phase modulation (XPM), four-wave mixing (FWM), and non-steady-state modulation. Applications that utilize the Kerr effect include optical parametric amplification, frequency conversion, phase coupling, pulse compression and generation, and optical soliton transmission. The design of highly nonlinear optical fibers needs to consider the following aspects: first, the optical fiber must have high nonlinearity to obtain effective nonlinear interactions; second, the optical fiber must have low loss to increase the effective action length Leff. Third, for various applications, the optical fiber must have matching dispersion characteristics. Finally, the nonlinear optical fiber must have low polarization mode dispersion (PMD). For silica-based highly nonlinear optical fibers, the design of the refractive index profile plays an important role in meeting the above requirements. In the design of high nonlinear optical fiber, a small core effective area Aeff, a low dispersion slope and a cutoff wavelength much smaller than the working wavelength must be achieved at the same time. High nonlinear optical fiber not only has high nonlinearity, but also has a very low dispersion slope. A flexible W-shaped profile design is adopted to introduce a low refractive index inner cladding around the step refractive index core.
