“…Combining practical material constraints with the results from numerical simulations, we found that Schott LLF1 glass is an excellent option as a cladding medium [42]. When the core diameter is reduced to wavelength-scale dimensions, the SF57-LLF1 combination provides a high enough index-contrast and hence a strong enough waveguide dispersion to compensate for the core material dispersion.…”

We review our recent progress in the development of lead silicate glass fibers with high nonlinearity and tailored near-zero dispersion at telecommunication wavelengths, encompassing holey, all-solid microstructured and W-type fiber designs. The fabrication techniques and relative merits of each fiber design are described in detail. The optical properties of the fabricated fibers are assessed both experimentally and through accurate numerical simulations. The significant potential of lead silicate highly nonlinear fibers for all-optical signal processing at telecommunication wavelengths is shown via a number of key experimental demonstrators.

This manuscript presents a ring-core Bragg Fiber (RC-BF) for orbital angular momentum (OAM) modes propagation and supercontinuum generation. The proposed RC-BF is composed of alternating layers of soft glasses SF57 and LLF1 to render high nonlinearity to the fiber. Mode analysis using fullvectorial finite element method resulted in obtaining HE/EH modes to support vector modes as well as orbital angular momentum modes. The optimized fiber supports 22 OAM modes and exhibits a zerodispersion wavelength (ZDW). The small effective area of Fiber 3 aided in achieving the highest nonlinearity, γ = 91.51 W −1 km −1 . A near-infrared supercontinuum is generated with a 35 dB flatness over a bandwidth of ∼1087 -2024 nm in a 20 cm long RC-BF using a chirp-free hyperbolic secant pulse of width 200 fs and peak power of 5 kW.INDEX TERMS Bragg fiber, finite element method, OAM modes, zero-dispersion wavelength, supercontinuum generation.

“…With a core diameter of 1.63µm, the fibre showed high nonlinearity γ of 820W -1 km -1 at 1.55µm and a normal dispersion profile across all wavelengths. At ~1.52µm the dispersion slope DS of the fibre was zero and the dispersion D was -2.6ps/nm/km [5]. Whilst, this work was highly encouraging, two important technical issues remained to be resolved.…”

“…According to the numerical simulation [5], in order to achieve both near-zero dispersion (D) and dispersion slope (DS) at 1.55µm in a W-type index profiled fibre based on SF57/LLF1/SF6 glasses, the optimized core diameter d core should be between 1.64-1.66µm. This means that the fibre core diameter and correspondingly the fibre outerdiameter (OD) should be precisely controlled within a range of ±0.6%.…”

“…Unfortunately, all earlier reported non-silica glass HNLFs have possessed either a dispersion shifted profile [2] or a highly normal dispersion profile [3], either due to an inadequate index-contrast between the core and the cladding [3], or difficulty in controlling the dimensions of a holey cladding with adequate precision [2]. We previously reported fabrication of the first single-mode non-silica glass HNLF with flatted, near-zero dispersion profile at 1.55µm [5]. The fibre had an all-solid W-type index profile (see Fig.1(a)) with a high index contrast.…”
