The Sixth Generation (6G) networks have identified the use of frequency range between 95 GHz and 3 THz with a targeted data rate of 1 Terabytes/second at the access network for holographic video applications. As is demands broadening of spectrum at the core network, this paper proposes a Supercontinuum Generation (SCG) through photonic crystal fiber (PCF) as it provides excellent broadening of the optical spectrum. Discussed in the paper is supercontinuum generation at high pumping power as per the standards specified by the International Telecommunications Union (ITU). The proposed PCF is designed with silicon nanocrystal core and the cladding microstructures is arranged in a fusion approach to effectively optimize the optical parameters such as dispersion, nonlinearity, birefringence, group velocity dispersion, and confinement loss. The fused cladding comprises of a flower‐cladding assembly in which air‐holes arrangement is inspired from petals in a pleated structure. Such arrangement is shown here to provide high nonlinearity and negative dispersion for high power supercontinuum generation. The novel nanocore assembly with improved structural constraints delivers a non‐linearity of 6.37×106 W‐1km‐1 and a negative dispersion of ‐142.1 (ps/nm‐km) at 1550 nm. Moreover, a supercontinuum spectrum is generated using different pulse widths ranging from 350 ps to 650 ps with 25kW pump power for PCF lengths of 10 mm and 15 mm.This article is protected by copyright.

“…Birefringence is obtained by disrupting the symmetrical cross-section or increasing the difference between the x-and y-polarized modes, various methods have been investigated to improve birefringence, such as adjusting the air holes (e.g. size, shape and distance) or introducing different shape or size air holes in the core [8][9][10]. Agbemabiese et al [11] proposed a PCF with birefringence of 2.018 × 10 −2 , and nonlinear coefficient is 40.68 W −1 km −1 .…”

This study introduces a Ge20Sb15Se65 chalcogenide-glass-based photonic crystal fiber (PCF) with high birefringence and nonlinearity and ultra-low confinement loss, in which two elliptical air holes are added in the core. The propagation properties of the proposed PCF are investigated in mid-infrared range (3.0–5.0 μm) using the finite element method (FEM). Simulation results indicate that optimizing structural parameters can increase the birefringence and nonlinear coefficient to a maximum of 3.16×10−1 and 5937 W-1km-1 (in y-polarization mode), respectively, a significantly low confinement loss reach 10-14 dB/m at 3.0μm wavelength, there can obtain one zero dispersion wavelength in the study band, and the designed structure can be fabricated using available technology. The designed PCF will have promising application in mid-infrared fiber fields, optical communication, super-continuum generation, precision, and nonlinear optics.

“…Moreover, the study revealed the tunability of the photonic crystal fiber structure to achieve sensing responses at different wavelengths, thereby enhancing the sensor's multifunctionality. In 2019, Yu B. et al proposed a novel photonic crystal fiber characterized by high birefringence, nonlinear properties, and ultra-flat dispersion, as described in reference [6]. This fiber design successfully achieved ultra-flat dispersion across a broad wavelength range while also possessing a remarkably high nonlinear coefficient.…”
