“…Similarly to the general procedure in isotropic media [9], we want to eliminate E z from Eqs. (1) and (2) to obtain a simple propagation equation involving only the transverse field E β . Before doing this, let us split the birefringent media in a series of slabs normal to the z-direction and assume that the permittivity tensor is z-independent in each slab -thereby greatly simplifying the derivation of the propagation equation in each slab.…”

“…On the other hand, BPM allows accurate simulation of light propagation on much coarser meshes provided that light don't deviate too much from a given reference direction of propagation. BPM is very well established in isotropic media, with a number of sub-class of methods based on Finite-Difference [1], Finite-Element [2] or Fast-Fourier-Transform [3]. Among these methods, paraxial BPM makes use of the Slowly-Varying-Amplitude-Approximation to yield methods which are very efficient but limited in terms of accuracy, while wide-angle BPM is a class of methods which are more accurate (but a bit more expansive) [4].…”

“…BPM is widely used in isotropic systems and very popular in waveguiding. Implementations based on fast Fourier transform [7], finite difference [8,9], or finite elements [10,11] exist. However, in birefringent material, the anisotropic nature of the permittivity tensor complicates the implementation of the BPM method.…”

“…First, our propagation model makes minimal assumptions on the electromagnetic fields in question, unlike the scalar beam propagation method (BPM, see [53,58,48,64,4] and references therein), which assumes a polarization maintaining propagation of the electromagnetic fields in an optical fiber, whereas our treatment is truly vectorial. Though both semi-vectorial and full vectorial BPM approaches have already been implemented (see [36,37,56,57,26] and references therein), we are introducing a fiber model that is a full boundary value problem rather than an initial value problem. In addition, we employ 3D isoparametric curvilinear elements to model the curved fiber (core and inner cladding) geometry, which can also later be used for studying microstructure fibers or hollow-core gas-filled fiber lasers.…”
