“…More recently, PCFs have transitioned from the confines of the laboratory to find utility in various fields such as optical communication, fiber light sources, fiber optic sensors, non-linear devices, and opto-fluidic devices [5][6][7]. Moreover, these fibers play a crucial role in the development of broad supercontinuum (SC) sources [8][9][10], which have found applications in a wide range of fields, including optical coherence tomography, optical metrology, and spectroscopy [11][12][13].…”

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.

This study presents a new square‐lattice photonic crystal fiber (PCF) with a nitrobenzene core. Considering the non‐uniformity of the air hole diameter, this new design allows the characteristic quantities to be optimized simultaneously to ensure near‐zero dispersion, a small effective mode area, and low loss for efficient spectral broadening. The spectrum broadens significantly at peak powers many times lower than in previous studies. Based on the obtained results, two optimal PCFs are proposed and validated in detail for supercontinuum generation (SCG). The first fiber #F1 operates in an all‐normal dispersion regime with a pump wavelength of 1.3 µm.It produces a spectral supecontinuum (SC) from 0.726 to 1.649 µm with a pulse duration of 90 fs and a peak power of 133 W. Meanwhile, the second fiber #F2 operates in anomalous dispersion regime with a pump wavelength of 1.61 µm. With a low peak power of 300 W and a pulse duration of 150 fs, the fiber #F2 provides SC generation with bandwidth from 0.805 µm to 3.970 µm. The proposed fibers are suitable for all‐fiber SC light sources, respectively, and may lead to new low‐cost all‐fiber optical systems.
