“…Coherent supercontinuum in the mid-infrared can be obtained with chalcogenide fibers, albeit exotic pump wavelengths are required and these glasses do not transmit at wavelengths shorter than 1.0 µm [19,24]. Recently, modulation instability driven supercontinuum, based on cascaded silica, chalcogenide and fluorozirconate glass fibers has been demonstrated [25]. This concept could be adapted to the ANDi supercontinuum pumped with ultrafast thulium-doped fiber lasers.…”

“…Several other pumping schemes have been investigated to generate Mid-IR supercontinua. In 2016, Petersen et al used a two-cascading configuration, based on a 1.55-µm laser-diode-pumped thulium-doped silica fiber and a Zr-Ba-La-Al-Na fluoride (ZBLAN) fiber, to pump a chalcogenide MOF, which generated a Mid-IR supercontinuum up to 4.4 µm [45]. By comparing the output spectra of ZBLAN fibers with different chromatic dispersions, it was concluded that solitons located in the long-wavelength part of the pump are essential for the effective generation of the supercontinuum.…”

The mid-infrared spectral region is of great technical and scientific importance in a variety of research fields and applications. Among these studies, mid-infrared supercontinuum generation has attracted strong interest in the last decade, because of unique properties such as broad wavelength coverage and high coherence, among others. In this paper, the intrinsic optical properties of different types of glasses and fibers are presented. It turns out that microstructured chalcogenide fibers are ideal choices for the generation of mid-infrared supercontinua. The fabrication procedures of chalcogenide microstructured fibers are introduced, including purification methods of the glass, rod synthesis processes, and preform realization techniques. In addition, supercontinua generated in chalcogenide microstructured fibers employing diverse pump sources and configurations are enumerated. Finally, the potential of supercontinua for applications in mid-infrared imaging and spectroscopy is shown.

“…However, most of these mid-IR SC sources have been demonstrated using bulky mid-IR pump sources such as optical parametric oscillators (OPO) and amplifiers (OPA). Mid-IR fiber lasers and cascaded fiber systems have recently emerged as attractive and promising solutions for practical and commercial applications [25][26][27][28][29][30][31][32][33][34][35]. These fiber lasers-based systems indeed open routes to practical, table-top and robust mid-IR supercontinuum sources with high spectral power density.…”

Mid-infrared supercontinuum (SC) sources in the 2 to 20 µm molecular fingerprint region are in high demand for a wide range of applications including optical coherence tomography, remote sensing, molecular spectroscopy, and hyperspectral imaging. In this work, we investigate mid-IR SC generation in a cascaded silica-ZBLAN-chalcogenide fiber system directly pumped with a commercially-available 460-ps pulsed fiber laser operating in the telecommunications window at 1.55 µm. This fiber-based system is shown to generate a flat broadband mid-IR SC covering the entire range from 2 to 10 µm with several tens of mW of output power. This technique paves the way for low cost, practical, and robust broadband SC sources in the mid-IR without the requirement of mid-infrared pump sources or Thulium-doped fiber amplifiers. We also describe a fully-realistic numerical model used to simulate the nonlinear pulse propagation through the cascaded fiber system and use our numerical results to discuss the physical processes underlying the spectral broadening in the cascaded system. We conclude with recommendations to optimize the current cascaded systems based on the simulation results.
