“…They are due to either sidewall scattering/surface smoothness and multiphonon absorption [1,12] or absorption in the polymer coating [14,19], significantly impacting their FOM. Soft glass suspended core fibers (SCFs) with low loss have been fabricated in recent years [16,20,21]. Due to the large refractive index difference, such SCFs are highly multimode, which both limits the amount of power effectively coupled to the fundamental mode and affects the phase matching condition of the parametric process [20].…”

Due to the large refractive index difference, such SCFs are highly multimode, which both limits the amount of power effectively coupled to the fundamental mode and affects the phase matching condition of the parametric process [20]. The large air holes also allow an extended contact area with the atmosphere, such that strong water absorption and crystallization were found to severely degrade their nonlinear optical performance [22].…”

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.

“…The nonlinear parameter γ = 2πn 2 /λA eff , (n 2 is the nonlinear refractive index, A eff is the effective area of the mode and λ is the wavelength) permits to compare the non-linear character of the different fibers. Thus, the nonlinear parameter is equal to 70 W −1 km −1 in silica MOF [23] while in chalcogenide MOF it can be as large as 46 000 W −1 km −1 [24] (Figure 4(b)). The Figure 3.…”

“…A transfer function of the intensity of the Mamyshef regenerator was obtained, but the average power needed to observe all-optical regeneration was much higher than the damage threshold of the fiber. Concerning wavelength conversion, others studies have investigated four wave mixing (FWM) effects [24,29,32]. In this case, both pulsed pump (λ 1 ) and CW source (λ 2 ) were injected in a chalcogenide MOF.…”

The combination of the unique optical properties of chalcogenide glasses, in terms of infrared transmission and optical non-linearity, with the original guiding properties of microstructured optical fibers leads to a new category of fibers with promising applications in mid-infrared optics. The recent developments on chalcogenide microstructured optical fibers are exposed and discussed with regards to mid-IR guiding, infrared light transport and delivery, generation of new infrared sources, and infrared spectroscopy.

Efficient Four-Wave Mixing in a Ultra-Highly Nonlinear Suspended-Core Chalcogenide Fiber

Abstract: International audienceWe report a chalcogenide suspended-core fiber with a record Kerr-nonlinearity of 46 000 W-1km-1 and attenuation of 0.9 dB/m. Four-wave-mixing efficiencies of -5.6 dB at 10 GHz and -17.5 dB at 42.7 GHz are obtained
