“…Maximum differences were found when higher refractive contrasts were considered, which could be due to the overestimation of the optical power transported in the core region of the rods with high refractive contrasts, which affects the calculation of the intensity-dependent perturbation. Experimental tests reported in [25] show that effectively high nonlinearities are expected when full-vectorial Kerr effect description is included.…”

is paper discusses an alternative method for calculating modal parameters in optical fibers such as propagation constants, transverse distributions, and anisotropy, due to linear and nonlinear phenomena acting as perturbations caused by doped silica regions. is method is based on a Hamiltonian formulation of the Helmholtz equation and the stationary perturbation theory, which allows a full-vectorial description of the electric field components when linear anisotropic inhomogeneities and Kerr nonlinearity are included. Linear and nonlinear parameters can be found for each propagating mode, and its accuracy has been successfully tested when compared to numerical calculations from the vector finite element method, and the results are published in the literature. is method facilitates the calculation of the spatial-distributed perturbation effects on individual electric field components for each propagating mode.

“…These glasses have invariably been used in either step-index [70][71][72][73] or photonic crystal fibre [74][75][76] designs, exhibiting up to three orders of magnitude higher nonlinearity than conventional silica singlemode fibres. Tapering of the waist diameter of such fibres has also been used to boost the nonlinear coefficient still further [77,78].…”

Summary:In this Chapter we review the need, general principles and approaches used to regenerate phase encoded signals of differing levels of coding complexity. We will describe the key underpinning technology and present the current state-of-the-art, incorporating an appropriate historic perspective throughout. The chapter finishes with a discussion of emerging research trends and broader future perspectives.

“…We call this structure a 'hexagonal wagon wheel' (HWW). The HWW geometry is based on previous work [19] which focused on designing dispersion engineered fibers for supercontinuum generation in the mid infrared [20]. It consists of a suspended core containing a ring of holes, as shown in Fig.…”
