Analysis of Spatially Doped Fused Silica Fiber Optic by Means of a Hamiltonian Formulation of the Helmholtz Equation

Figure 4

Effective refractive index of the optical fiber with uniaxial birefringence having the same spatial dependence of Figure 1(b) versus obtained by the HFHE formulation (lines) and calculated by the vector FEM (dots). Solid lines correspond to component and dashed lines to component.
