Mid-IR supercontinuum between 1 and 5 µm in step index tellurite fibres for greenhouse or pollutant gases detection (Conference Presentation)

Arnaud Lemière Paul Froidevaux Bertrand Kibler Frédéric Désévédavy Jean‐Charles Jules

Development of broadband supercontinuum sources has been studied since decades for its high application potential in various fields like spectroscopy, medical science and others. First experiments were made with silica but the results shown the need to find new materials for supercontinuum generation in the IR wavelength range. Two types of materials have been found interesting for supercontinuum generation: chalcogenide and tellurite glasses. These materials have a high non-linear refractive index and a good transmission in infrared which provides a high potential for applications. Bulks tellurite glasses transmit until 5µm while bulks chalcogenide glasses transmit until 12-20µm depending on their composition. We report here the synthesis of low-OH step-index tellurite fibers and their linear and non-linear characterization. The synthesis is firstly realized by build-in-casting in a glovebox which allows to get a large-core preform(∅clad/∅core  2) and a large core corresponding fiber(∅core  60µm). Then, the rod-in-tube technique allows, from the jacketing of the stretched initial preform, to get a small-core preform and subsequently a small core fiber (∅core  3.5µm). The minimum of losses of the large-core fiber is below 1dB/m, the IR transmission wavelength exceeds 4 µm on several meters of fibers and reaches more than 5 µm on small samples (several centimeters long). We have developed core-clad composition with a large refractive index difference (∆n=0.132) which provides a high confinement in our step-index fibers. We discuss the supercontinuum generation in these fibers exploiting numerical simulations based on the generalized nonlinear Schrödinger equation and then we present the supercontinuum experimental results obtained between 1 and 5µm. Most of pollutant and greenhouse gases emitted by human activity, including methane, carbon dioxide and nitrous oxide, absorbs in the mid-IR. The spectroscopic experiments realized on the gases through supercontinuum generation between 1 and 5 µm are presented.

Dispersion-engineered step-index tellurite fibers for mid-infrared supercontinuum generation from 1.5 to 4.5 μm

Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF) (2018)

We present the experimental development of dispersion-engineered tellurite fibers based on a simple step-index profile for mid-infrared supercontinuum generation. A supercontinuum spanning from 1.5 to 4.5 μm is obtained in a 12-cm-long fiber.

Tellurite-Based Core-Clad Dual-Electrodes Composites Fibers

2022 Photonics North (PN) (2019)

Anthony Maldonado Arnaud Lemière Frédéric Désévédavy J.-C. Jules Grégory Gadret

Here, we propose to design a new class of glass/metal composite fibers for all-guided optical-electrical signals. The objective is to combine metal and glass materials by using additive manufacturing approach to engineer multimaterials fibers. Thus, after manual insertion of metallic electrodes into the tellurite glass preform, we can obtain the first tellurite-based core-clad dualelectrode composite fiber made by direct, homothetic preform-to-fiber thermal co-drawing.

Mid-Infrared supercontinuum absorption spectroscopy beyond 7 µm based on free Arsenic chalcogenide fiber

EPJ Web of Conferences (2023)

Rémi Bizot Frédéric Désévédavy Arnaud Lemière Esteban Serrano Damien Bailleul

Mid-Infrared methane (CH 4 ) spectroscopy results were obtained in band III beyond 7 µm. To achieve this, the generation of supercontinuum covering the spectral range between 5 and 12 µm was realized by using purified chalcogenide optical fibers free of highly toxic elements such as arsenic and antimony. Besides a pumping with an optical parametric amplifier, an all fibered pumping scheme has also been investigated. In both configuration, supercontinuum absorption spectroscopy experiments have allowed for CH 4 sensing, concentration as low as 14 ppm has been detected.

Nonlinear glasses-based microstructured or step-index optical fibers: mid-IR supercontinuum generation and IR spectroscopy applications

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2017)

F. Smektala Bertrand Kibler Clément Strutynski J. Picot-Clémente Arnaud Lemière

We present an overview of the fabrication process and characterization of germanate, germanate-tellurite and tellurite microstructured fibers or step-index fibers with different index contrasts. For microstructured fibers, we exploit the generated SC for methane spectroscopy measurements in the mid-infrared by means of the supercontinuum absorption spectroscopy technique. We demonstrate also an ageing process of microstructured fibers in ambient atmosphere. For stepindex fibers, several compatible core/cladding glasses were explored for fiber manufacturing with a dehydration process, allowing the drawing of low-OH tellurite fibers. We report both numerical and experimental demonstrations supercontinuum (SC) generation in these fibers. Finally we report our latest results in the generation of SC until 5.3 μm in a step-index tellurite fiber.

Characterization of biodegradable core–clad borosilicate glass fibers with round and rectangular cross‐section

Journal of the American Ceramic Society (2023)

Abstract Here, we report on core–clad bioactive borosilicate fibers, that we have prepared both with round and rectangular cross‐section profile. The exposed approach, which relies on the stacking and drawing of glass slabs, demonstrates our ability to develop bioactive‐based glass fibers with tailored cross‐section profiles. Tens‐of‐meters‐long fibers were successfully drawn, although suffering from elevated losses in the case of the rectangular ones. The response of the fibers in simulated body fluid was studied for both geometries. We found that a round cladding can act as protective layer, tempering effects of the corrosion. We also noticed that rectangular fibers are more prone to degradation, the enhanced corrosion beginning from their sharp corners as they accumulated residual tensile stress during drawing. To the best of our knowledge, this is the first report on the effect of residual tensile stresses from surface tension deformations applied to the corrosion of rectangular fibers. As geometry plays a critical role on the biodegradation behavior of the fiberglass, we believe the enclosed results could lead to the design of fiber devices with tailored cross‐section profile in order to tune their rate of degradation on solely based geometrical effects.

Mid-infrared supercontinuum generation from 2 to 14 μm in arsenic- and antimony-free chalcogenide glass fibers

Journal of the Optical Society of America B (2019)

Arnaud Lemière Frédéric Désévédavy Pierre Mathey Paul Froidevaux Grégory Gadret

We demonstrate the fabrication of arsenic- and antimony-free chalcogenide glasses compatible with glass fiber processing. Optical fibers with distinct index profiles are presented and characterized, namely, single-material fibers with or without a suspended core and standard step-index fibers with varying core diameter. In addition, we evidence their potential for nonlinear photonic devices in the mid-infrared spectral region by means of supercontinuum generation experiments in the femtosecond regime. Spectral broadenings extend on several octaves in the mid-infrared from 2 to 14 μm.

Mid-infrared two-octave spanning supercontinuum generation in a Ge–Se–Te glass suspended core fiber

Laser Physics Letters (2019)

Arnaud Lemière Frédéric Désévédavy Bertrand Kibler Pierre Mathey Grégory Gadret

We report on both the fabrication and the application of a Ge–Se–Te glass-based suspended core fiber for mid-infrared supercontinuum generation. A two-octave spanning mid-infrared light source (from 3.25 to 13 µm) is experimentally demonstrated by pumping the chalcogenide fiber with sub-100 fs pulses at 8.6 µm. Numerical simulations of nonlinear pulse propagation as well as fiber properties are also provided and support experimental measurements.
