“…power handling of chalcogenide fibers has been an important concern. It was believed that intensities were limited to the order of kW∕cm 2 [30,31], greatly hindering the potential of this extremely nonlinear and high-viscosity [31] MIR glass material. Recently, based on the parameters provided in Ref.…”

The persistent growth of interest in the middle infrared (MIR) is stimulating the development of sources and components. Novel waveguides and fibers for the efficient use of nonlinear effects in the MIR are being intensively studied. Highly nonlinear silica fibers have enabled record performances of highly versatile parametric processes in the telecommunication band. However, no waveguiding platforms (to our knowledge) have yet solved the trade-off among high nonlinearity, low propagation losses and dispersion in the MIR. As single waveguide designs have not yet hit this particular optimal point, only pulsed-pumped demonstrations have been carried out, hindering any application requiring narrow linewidth, continuous-wave (c.w.) operation, or signal modulation. Here, we show MIR c.w. parametric amplification in a Ge 10 As 22 Se 68 tapered fiber. Leveraging state-of-the-art fabrication techniques, we use a photonic crystal fiber (PCF) geometry combining high nonlinearity and low dispersion, while maintaining single mode and low losses in the short-wave IR and MIR. We experimentally demonstrate 5 dB signal amplification and 3 dB idler conversion efficiency using only 125 mW of pump in the 2 μm wavelength range. Our result is not only the first c.w. parametric amplification measured at 2 μm in any waveguide, but it also establishes GeAsSe PCF tapers as the most promising all-fibered, high-efficiency parametric converter for advanced applications in the MIR.

“…Supercontinuum generation (SCG) in chalcogenide glass fibers have attracted a great deal of interest due to their nonlinear properties and wide mid-infrared (MIR) transmission band across the molecular fingerprint region to above 14 µm [1][2][3][4][5]. Together with the high beam quality and intensity of a fiber-delivered beam SCG in chalcogenide fibers has opened the prospects for new powerful MIR analytical tools for broadband fundamental vibrational spectroscopy [6], optical coherence tomography [7], and hyperspectral microscopy [8,9].…”

“…The most commonly reported chalcogenide glasses used in optical fibers are As 2 S 3 [24-29] and As 2 Se 3 [4,[30][31][32], where As 2 Se 3 has both a stronger nonlinearity and longer MIR transmission edge, albeit at the cost of a longer material ZDW of ~7 μm compared to ~5 μm in As 2 S 3 [1][2][3]. Consequently, efforts have been made to reduce the ZDW of chalcogenide fibers by utilizing microstructured design, such as suspended-core fibers [31,32].…”

“…These light sources are often based on ultra-broadband nonlinear spectral conversion in fluoride, tellurite, and chalcogenide glass (ChG) fibers [1][2][3][4]. Among different glass compositions, the ChGs have the highest nonlinearity and the broadest transparency ranges which allow operating at wavelengths where fluoride and tellurite glasses cannot be transparent [1]. To date, the broadest SC demonstrated in ChG fibers extends from ~2 to 16 μm [4].…”

Highlights:As-Se tapered suspended-core fibers were designed for mid-IR SC generation. Parameters of the produced fibers were studied experimentally and numerically. SC in the 1-10 μm range with 150-fs 100-pJ pump at 2 μm was obtained numerically. Experiments on spectral broadening of pump pulses at 1.57 μm were performed. AbstractWe designed and developed tapered suspended-core fibers of high-purity As 39 Se 61 glass for supercontinuum generation in the mid-IR with a standard fiber laser pump source at 2 μm. It was shown that microstructuring allows shifting a zero dispersion wavelength to the range shorter than 2 μm in the fiber waist with a core diameter of about 1 μm. In this case, supercontinuum generation in the 1-10 μm range was obtained numerically with 150-fs 100-pJ pump pulses at 2 μm. We also performed experiments on wavelength conversion of ultrashort optical pulses at 1.57 μm from Er: fiber laser system in the manufactured As-Se tapered fibers. The measured broadening spectra were in a good agreement with the ones simulated numerically. IntroductionThe mid-infrared (IR) supercontinuum (SC) laser sources have important applications in both basic science and industry. These light sources are often based on ultra-broadband nonlinear spectral conversion in fluoride, tellurite, and chalcogenide glass (ChG) fibers [1][2][3][4]. Among different glass compositions, the ChGs have the highest nonlinearity and the broadest transparency ranges which allow operating at wavelengths where fluoride and tellurite glasses cannot be transparent [1]. To date, the broadest SC demonstrated in ChG fibers extends from ~2 to 16 μm [4]. It is well-known that not only the nonlinearity and transparency range impact on spectral broadening; the zerodispersion wavelength (ZDW) location with respect to a central pump wavelength is also of great importance for SC width [5,6]. Operation in the anomalous dispersion regime often allows obtaining a broader spectrum in comparison with normal dispersion. In this pumping scheme, SC generation is dominated by the soliton dynamics. To generate ultra-broadband SC in solid step-index ChG fibers having ZDW near the material ZDW (which is significantly beyond 4 μm, for example, 4.81 μm for As 2 S 3 , 7.5 μm for As 2 Se 3 , and >7.5 μm for Te-based ChG [1]), mid-IR optical parametric oscillators and amplifiers have been employed [7,8]. However, if it is desirable to use a pump source at shorter wavelengths than material ZDW, microstructured or/and tapered fibers with blue-shifted ZDW can be implemented. Suspended-core fiber (SCF) geometry is widespread for dispersion management. So, SC spanning 1.7-7.5 μm has been obtained in As-Se SCF with ZDW of 3.5 μm pumped at 4.4 μm [9]. In this paper, the design, development, and manufacturing of tapered SCF with a thin waist core diameter of about 1 μm of the high-purity As-Se glass are reported. The As-Se glass has a broad spectral transparency range (0.85-17.5 μm for absorption coefficient level of 1 cm
