Investigation of defective hybrid cladding with silicon nanocrystal PCF for supercontinuum generation

Abstract

Defective hybrid cladding through a silicon nanocrystal-core-structured photonic crystal fiber intended for high pump power supercontinuum proliferation is discussed in this paper. The cladding comprehends a hybrid approach of a hexagonal air hole in the outer section and a petal-structured air hole in the inner layer with a twisted pattern. Such a procedure with an air hole in the cladding section with a silicon nanocore displays high nonlinearity and negative dispersion at the communication window for varying pulse widths with 20 kW pump power. The impact of structural parameters of the proposed structure on the optical constraints is discussed, namely, dispersion, nonlinearity and group-velocity dispersion for wavelengths ranging from 0.45 µm to 1.85 µm. The proposed structure with optimized structural parameters provides high nonlinearity of about 6.38 × 106 W−1 km−1 with negative dispersion of −70.19 ps (nm km)−1 at 1550 nm.

Structural Analysis of Nano Core PCF With Fused Cladding for Supercontinuum Generation in 6G Networks

“…Supercontinuum generation in PCF with novel guidance properties has made the spectrum broadening a practically feasible solution. From the results reported in literature (A. Rajesh et al., 2021), it is clear that PCF has made a remarkable development in both technical and essential studies of nonlinear optics. In concert, it also paved the way for developing novel and flexible instruments commercially and it also pursues to instigate the various technical fields.…”

Theoretical Investigation of Bandwidth in Multimode Step-Index Silica Photonic Crystal Fibers

“…In practice, optical dispersion and birefringence of PCFs is often investigated [14][15][16][17]. Nowadays, PCFs are important since they can be implemented for many applications, such as supercontinuum light generation [18][19][20], light wavelength conversion [21,22], optical fluids [23], and different sensing area [24]. The width of the PCF material between the holes of the cladding determines the NA of the PCF, which is normally limited to NA 0.5-0.6 [25][26][27].…”
