“…Chalcogenide glasses have the additional virtue of being vitreous in nature, which enables them to be fiber-drawn. This distinctive property makes them among the select few materials capable of transmitting for far and mid-infrared light [21][22][23]. Chalcogenide glasses are multicomponent inorganic materials mainly composed of elements such as S, S, Te, As, Sb, Ge, and Si [24][25][26].…”

This paper presents a new design of Ge20Sb5Se75 large-solid-core photonic crystal fiber (PCF) with a 1st-ring-removed square lattice. Using the full vector finite element method for anisotropic perfectly matched layers, we numerically examine the dispersion characteristics of the PCF in the wavelength range spanning from 1.5 µm to 6.0 µm. The results reveal that photonic crystal fibers exhibit a variety of dispersion properties, including all-normal and anomalous dispersion, featuring one or two zero dispersion wavelengths (ZDWs). We propose two designs with optimal dispersion characteristics based on our numerical simulations. These designs have small lattice constants (Ʌ = 1.0 µm; Ʌ = 1.5 µm) and low fill factors (d/Ʌ = 0.3; d/Ʌ = 0.35). Furthermore, these selected fibers offer high nonlinearity and low confinement loss, making them excellent candidates for a wide range of optical applications.

“…Photonic crystal fibers have numerous applications in science and engineering [5][6][7][8][9] because of their outstanding optical properties. The PCF's design versatility via adjusting their lattice parameters to achieve exceptional optical properties, such as endlessly monomodal propagation, high nonlinearity, low confinement loss, and tunable chromatic dispersion profile, allow PCFs to be an excellent nonlinear medium to enhance supercontinuum (SC) generation performance [10][11][12][13][14][15][16]. In most studies on SC generation via PCFs, silica has been used as a common background material.…”

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.
