“…Finally, a more complex sandwich-like fiber architecture is produced from the combination of Polyether sulfone and a TZN75 tellurite glass (glass composition 75 TeO 2 –20 ZnO–5 Na 2 O mol %). The preform is prepared from two rectangular glass plates and a 50 µm thick PES film using a modified stack-and-draw method 31 . SEM images of the fabricated fiber are shown in Fig.…”

Among the different fundamental aspects that govern the design and development of elongated multimaterial structures via the preform-to-fiber technique, material association methodologies hold a crucial role. They greatly impact the number, complexity and possible combinations of functions that can be integrated within single fibers, thus defining their applicability. In this work, a co-drawing strategy to produce monofilament microfibers from unique glass-polymer associations is investigated. In particular, the molten core-method (MCM) is applied to several amorphous and semi-crystalline thermoplastics for their integration within larger glass architectures. General conditions in which the MCM can be employed are established. It is demonstrated that the classical glass transition temperature compatibility requirements for glass-polymer associations can be overcome, and that other glass compositions than chalcogenides can be thermally stretched with thermoplastics, here oxide glasses are considered. Composite fibers with various geometries and compositional profiles are then presented to illustrate the versatility of the proposed methodology. Finally, investigations are focused on fibers produced from the association of poly ether ether ketone (PEEK) with tellurite and phosphate glasses. It is demonstrated that upon appropriate elongation conditions, the crystallization kinetics of PEEK can be controlled during the thermal stretching and crystallinities of the polymer as low as 9 mass. % are reached in the final fiber. It is believed such novel material associations as well as the ability to tailor material properties within fibers could inspire the development of a new class of hybrid elongated objects with unprecedented functionalities.

“…Thermal and optical properties show linear evolution with respect to the Nd 3+ concentration, allowing fine control of the glass transition temperature and of the refractive index. Core and cladding glasses were selected based on these investigations and a rectangular-core multimode optical fiber was manufactured using a modified stack-and-draw technique recently developed by our group [28]. Thereafter, femtosecond laser pumping was employed to demonstrate the generation of a large-band spectral broadening in these newly-developed fibers thanks to self-guided nonlinear effects.…”

Here we present the ability of Nd3+-doped zinc-phosphate glasses to be shaped into rectangular core fibers. At first, the physico-chemical properties of the developed P2O5-based materials are investigated for different concentrations of neodymium oxide and core and cladding glass compositions are selected for further fiber development. A modified stack-and-draw technique is used to produce multimode large rectangular-core optical fibers. Self-guided nonlinear effects acting as spatial beam reshaping processes occurring in these newly-developed photonic structures lead to the generation of spectral broadenings in the visible and near-infrared spectral domains.

“…Previous works have shown that the well‐known stack‐and‐draw method can be applied not only for the production of cylindrical fiber geometries, but also for the development of unusual all‐glass or multi‐material elongated architectures. [ 16 ] In this section, we take advantage of the stack‐and‐draw method to prepare a rectangular‐section preform. Five vitreous tellurite glass plates (one core cane and four cladding plates) are processed and assembled to build the preform as described in Figure a–I.…”

supercontinuum (SC) spectra. [2] In particular, SC generation with wavelengths covering all the visible domain and a large part of the silica transparency window has been demonstrated [3] : the spatially single-mode polychromatic beams have widely been employed for linear and nonlinear fluorescence imaging using femtosecond, picosecond, or subnanosecond pulses. [4,5] More recently, multimode optical fibers have also been considered for efficient imaging processes demonstration in the visible and near-infrared domain [6] ; in particular, two and three-photon fluorescence measurements have been demonstrated. Although coupling laser light into a multimode fiber is a relatively easy task, the output beam suffers from spatial and temporal distortions that bring severe limitations to the imaging resolution. Such drawback may be mitigated using optimization techniques such as deep-learning algorithms combined with spatial light modulators [7] ; one can also take advantage of nonlinear effects such as the spatial beam self-cleaning, already reported in the literature also for non-silica graded-index multimode fiber, [8] to reach nearly single-mode output beam, and consequently high transverse resolution images. However, the large core diameter of the multimode fiber requires the use of long spans to obtain significant spectral broadening, owing to the relatively low nonlinear
