“…Owning to the high nonlinearity and the combination of visible and mid-infrared transmission in certain chalcogenide glasses, hybrid chalcogenide-tellurite glass fibers have been demonstrated for tunable third-harmonic generation [57]. Tellurite oxide glass fibers, having narrower transmission windows than chalcogenides, but benefitting from better mechanical properties, have also been investigated for midinfrared SC generation up to about 5 μm [15,[58][59][60][61], as well in fiber parametric amplifiers [62]. It is worth noting that tellurite glasses are a particularly versatile group of materials for fibers.…”

An overview of the progress on pulse-preserving, coherent, nonlinear fiber-based supercontinuum generation is presented. The context encompasses various wavelength ranges and pump sources, starting with silica photonic crystal fibers pumped with 1.0 μm femtosecond lasers up to chalcogenide step-index and microstructured fibers pumped from optical parametric amplifiers tuned to mid-infrared wavelengths. In particular, silica and silicatebased all-normal dispersion (ANDi) photonic crystal fibers have been demonstrated for pumping with femtosecond lasers operating at 1.56 μm with the recorded spectra covering 0.9-2.3 μm. This matches amplification bands of robust fiber amplifiers and femtosecond lasers. The review therefore focuses specifically on this wavelength range, discussing glass and nonlinear fiber designs, experimental results on supercontinuum generation up to the fundamental limit of oxide glass fiber transmission around 2.8 μm, and various limitations of supercontinuum bandwidth and coherence. Specifically, the role of nonlinear response against the role of dispersion profile shape is analyzed for two different soft glass ANDi fibers pumped at more than 2.0 μm. A spatio-temporal interaction of the fundamental fiber mode with modes propagating in the photonic lattice of the discussed ANDi fibers is shown to have positive effects on the coherence of the supercontinuum at pump pulse durations of 400 fs. Finally, the design and development of graded-index, nanostructured core optical fibers are discussed. In such structures the arbitrary shaping of the core refractive index profile could significantly improve the engineering flexibility of dispersion and effective mode area characteristics, and would be an interesting platform to further study the intermodal interaction mechanisms and their impact on supercontinuum coherence for subpicosecond laser pumped setups.

“…Various soft-glass fibers made of fluoride [9][10][11], tellurite [12][13][14], and chalcogenide (ChG) glasses [15][16][17] have been used to generate MIR SCs, and numerous achievements have been accomplished. Fluoride and tellurite are both transparent in the wavelength range below 5.5 µm and thus, cannot be used for wavelengths longer than 5.5 µm.…”

A Review of Mid-Infrared Supercontinuum Generation in Chalcogenide Glass Fibers

et al. 2018

View full text Add to dashboard Cite

Chalcogenide glasses have the advantages of a wide transparency window (over 20 µm) and high optical nonlinearity (up to a thousand times greater than that of silica glasses), making them good candidates for mid-infrared supercontinuum generation. In this review, we describe both the history and recent developments in mid-infrared supercontinuum generation from chalcogenide fibers according to three kinds of fiber structures: step-index, microstructured and tapered fibers. We also review the coherence properties of mid-infrared supercontinuum generation and all-fiber supercontinuum sources based on chalcogenide fibers.

“…Most reports about tellurite glass fibers in the literature have been based on microstructured optical fibers pumped in the near-IR. [11][12][13][14][15] These fibers show enhanced nonlinearities due to the small core sizes and engineered zero dispersion wavelengths (ZDWs) below 2 µm, allowing for anomalous dispersion pumping with conventional laser systems. However, the enormous design flexibility to tailor the nonlinearity and the dispersion profile comes along with a limited spectral coverage of the wavelength region above 3 µm.…”

Solitonic supercontinuum of femtosecond mid-IR pulses in W-type index tellurite fibers with two zero dispersion wavelengths

We present a detailed experimental parameter study on mid-IR supercontinuum generation in W-type index tellurite fibers, which reveals how the core diameter, pump wavelength, fiber length, and pump power dramatically influence the spectral broadening. As pump source, we use femtosecond mid-IR pulses from a post-amplified optical parametric oscillator tunable between 1.7 μm and 4.1 μm at 43 MHz repetition rate. We are able to generate red-shifted dispersive waves up to a wavelength of 5.1 μm by pumping a tellurite fiber in the anomalous dispersion regime between its two zero dispersion wavelengths. Distinctive soliton dynamics can be identified as the main broadening mechanism resulting in a maximum spectral width of over 2000 nm with output powers of up to 160 mW. We experimentally demonstrated that efficient spectral broadening with considerably improved power proportion in the important first atmospheric transmission window between 3 and 5 μm can be achieved in robust W-type tellurite fibers pumped at long wavelengths by ultra-fast lasers.
