“…where Re[neff] is the real part of neff, which is the effective index of a guided mode calculated by means the FDE method, and c is the velocity of light in the vacuum. Obviously, by carefully selecting the geometry of the structure and changing the lattice parameters in the simulation, we achieved anomalous dispersion with double ZDWs, similar to that of Si et al [24], but it was not observed in other works [22,23]. The anomalous dispersion with two ZDWs is one of the outstanding advantages of this work, suitable for some SC generations with the influence of soliton-induced effects.…”

“…The effective mode area for the fundamental mode can be calculated according to Formula 4 [30], where E is the transverse electric field over the cross-section of the PCF In contrast, the minimum and maximum values of Aeff are 0.593 and 5.312 µm 2 when D is 16.07 and 64.28 µm. We achieved much higher nonlinear coefficients and much smaller effective mode areas than those in other works [22,24,32,33] with As2S3-based suspended-core PCFs.…”

In this paper, the nonlinear properties of photonic crystal fibers (PCF) with As2S3 substrate were analyzed numerically. With the suspended-core design, we achieve an anomalous dispersion regime with one or two zero-dispersion wavelengths, which is flat and has a small value at the investigated wavelength. The high nonlinear coefficient and very low confinement loss in the wavelength range of 1–3 µm, in comparison with other publications, are the outstanding advantages of these suspended-core PCFs. The highest nonlinear coefficient (28,527.374 W–1·km–1), smallest effective mode area (0.593 µm2), and low confinement loss (6.050 × 10–17 dB·m–1) at the wavelength of 1.55 µm were observed in the PCFs with a fiber diameter of 16.07 μm. Based on the numerical simulation results, we proposed two optimal structures suitable for supercontinuum generation.
