“…In all our examples, we have taken the solid material to be silica and the refractive-index of silica has been obtained using Sellmeier's coefficients (Fleming 1978). We have first obtained the modal effective index and have compared the accuracy of our results with those obtained using the ESI model (Birks et al 1997) and the scalar FEM (Aristizabel et al 2006). For the ESI model, the core radius is taken as 0.625 (Birks et al 1997).…”

We present an analytical model for the mode of index-guided microstructured fibers. This model exhibits essential symmetry features of the field unlike the commonly used equivalent step-index (ESI) model. The model is shown to be more accurate than the equivalent step-index (ESI) model in predicting the effective-indices of the mode. Results for the modal effective index, near and far fields and dispersion have been included.

“…(17) can be solved as an infinite waveguide where the refraction index is supposed constant along the propagation axis ( z -direction). Here, the electric field can be computed by FEM (See more details in [32][33][34]). To calculate the field by FEM, the fiber cross-section is discretized into small elements and Eq.…”

“…The birefringence maps are recovered by means of the elasto-optical theory [28][29][30][31][32]. Using these results, for each value of the external force, in the solution by FEM of the wave equation [33][34][35], the electric field distribution is obtained. All the allowed propagation modes in the SMMF are calculated and vectorially superposed in order to reconstruct the fiber speckle pattern for each stress condition.…”

Numerical modeling of fiber specklegram sensors by using finite element method (FEM)

Although experimental advances in the implementation and characterization of fiber speckle sensor have been reported, a suitable model to interpret the speckle-pattern variation under perturbation is desirable but very challenging to be developed due to the various factors influencing the speckle pattern. In this work, a new methodology based on the finite element method (FEM) for modeling and optimizing fiber specklegram sensors (FSSs) is proposed. The numerical method allows computational visualization and quantification, in near field, of changes of a step multi-mode fiber (SMMF) specklegram, due to the application of a uniformly distributed force line (UDFL). In turn, the local modifications of the fiber speckle produce changes in the optical power captured by a step single-mode fiber (SSMF) located just at the output end of the SMMF, causing a filtering effect that explains the operation of the FSSs. For each external force, the stress distribution and the propagations modes supported by the SMMF are calculated numerically by means of FEM. Then, those modes are vectorially superposed to reconstruct each perturbed fiber specklegram. Finally, the performance of the sensing mechanism is evaluated for different radius of the filtering SSMF and force-gauges, what evidences design criteria for these kinds of measuring systems. Results are in agreement with those theoretical and experimental ones previously reported.

“…10 PCF is endowed with certain properties like nonlinear effects for small mode area, large mode area for creating high-power optical beams, an enormous control over dispersion for variable air-hole diameter (d), and pitch (Λ). 11 Unlike conventional fiber, it is highly adaptable with reference to structural parameters, thus becoming suitable for theoretical modeling. Several numerical techniques have been established to evaluate the guiding properties of PCFs such as finite-difference time-domain method (FDTD), 12,13 finite element method (FEM), 13,14 effective index method (EIM).…”

SummaryWe report here the development of two computational tools PCFPS (Photonic Crystal Fiber Parameter Study) and PCFPA (Photonic Crystal Fiber Parameter Analysis), equipped with graphical user interface (GUI) for modeling of photonic crystal fiber. The tools are based on different structural parameters, and they provide characteristic analysis of the modal parameters from the structural parameters. The main feature of PCFPS is that it enables the user to find out the values of each defining modal parameter that has an immense contribution towards the manufacture of photonic crystal fiber. Additionally, PCFPA allows the user to observe the variation in the modal parameters with respect to the changes in structural parameters (such as d, Λ, d/Λ, and λ/>Λ). Besides their ease of use, these two schemes have high computational precision and adaptability, giving a novel platform to optical engineers to modulate the microstructured fibers according to their requirement.
