“…It is important to underline that the short-wavelength edge of the transmission band is determined by the resonance of the largest Germanium rods, while the long-wavelength one depends on the smaller ones. The same filtering properties have been numerically investigated [8], by calculating the overlap integral of the FM on the DSF fiber core, reported in Figure 5(b) for the wavelength range between 900 nm to 1200 nm, with a full-vector modal solver based on the finite element method [4,5]. Notice that the computed FM overlap integral shows a transmission band which is blue-shifted of about 50 nm with respect to the experimental results.…”

“…Then, the elasto-optical induced change of the refractive index in the transverse direction has been calculated. Finally a complex full-vector modal solver based on the finite element method, which exploits conformal mapping for bent-fiber modeling, and perfectly matched layers [4,5], has been used to calculate the bend losses. Figure 4(a) reports the bending losses BL of the two polarizations of the FM and the most detrimental HOM at 1064 nm as a function of the bending diameter.…”

The ALPINE project is developing innovative fiber lasers for the scribing of new thin film photovoltaic modules with the aims to push forward the European research and development of fiber laser systems and solar energy exploitation. The fiber lasers will be based on photonic crystal fibers, which are characterized by unusual and interesting light guiding properties exploited to deliver high power with excellent beam quality and high resonator stability and efficiency, and will be applied to substitute mechanical scribing steps in the photovoltaic module production. In addition, new photovoltaic thin film technologies is applied, which is based on cadmium telluride and copper indium diselenide materials. With a potential conversion efficiency just below that of crystalline silicon, these new material approaches are ready to enter the market with low manufacturing costs for immediate economic or environment impact.

The properties of a large mode area Yb-doped double-cladding hybrid photonic crystal fiber, with antisymmetric high-index inclusions, have been analyzed. Simulations, carried out through a finite-element based modal solver, and experimental measurements have demonstrated the narrow spectral filtering capability of this fiber, with a passband of about 80 nm in the Yb gain region. Moreover, high-order mode suppression has been demonstrated with a proper air-hole size. Finally, the stress-induced birefringence due to the Ge-doped rods used as high-index insets has been investigated, accounting for the polarization-maintaining behaviour of the manufactured fiber.

“…[7][8][9] Moreover, numerical analysis has demonstrated that anti-symmetric hybrid PCFs have interesting bending properties, 8-10 which need further investigations. In this paper a full-vector modal solver, based on the Finite Element Method (FEM), 11,12 has been applied to analyze the bending properties of a novel design of anti-symmetric double-cladding hybrid PCFs, where three rows of cladding air-holes have been replaced by high-index inclusions of different diameters on each side of the fiber core. Numerical results have demonstrated that the 3-row hybrid fibers provide a significantly better bending tolerance than other PCFs with similar mode-field diameter, as well as a stronger filtering effect with respect to the prior design with only one row of high-index resonators.…”

A novel design of Yb-doped double-cladding hybrid photonic crystal fibers, with three rows of high-index inclusions on each side of the core, has been numerically analyzed with a full-vector modal solver based on the finite element method. Simulation results have demonstrated that a stronger filtering effect and a higher bending tolerance can be obtained with an increased number of high-index resonators. Moreover, the unique bending properties of hybrid fibers with anti-symmetric design have been investigated and explained through the comparison with the ones of hybrid symmetric fibers, with high-index inclusions of the same dimension on both sides of the core.
