Due to the pronounced scientific and technical attention paid to mid-infrared spectral region, we focus on ultrawide mid-infrared supercontinuum generation in Αs40Se60 chalcogenide SIF and PCF-step index and photonic crystal fibersusing symmetrized split step Fourier method (S-SSFM). Simulations reveal, in response to launching 100 fs input pulses of 50kW peak powers, with near zero dispersion wavelengths centered about λ0 = 4.25 μm, into 50-mm long Αs40Se60 SIF and solid core PCF, 8.5 and 11-μm supercontinua can be achieved, respectively. Moreover, numerical results also show, when ultra-short pulses of center wavelengths λ0=12 μm are launched into those SIF and PCF, ripple free spectra as wide as 10 and 13 μm can be attained, respectively. These spectra are useful for safe spectroscopic medical imaging diagnosis such as early cancer diagnostics, and other spectroscopic applications such as gas sensing and food quality control.

“…In SCFs, dispersion profile optimization can be accomplished by changing the structural parameters, such as the fiber core diameter (d) and the bridge width (w) [90,91,134,135]. As can be seen from Figure 7, the calculated ZDWs of SCFs can be shifted to shorter wavelengths by reducing d and w to match the pump wavelength.…”

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

et al. 2018

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.

“…Various soft-glass fibers made of fluoride [14][15][16][17][18], tellurite [19,20], and chalcogenide (ChG) glasses [21][22][23][24][25] have been used to generate MIR SCs, and numerous achievements have been accomplished. Fluoride and tellurite are both transparent in the wavelength range of lower than 5.5 μm and thus may cannot be used in relatively long wavelengths.…”

Chalcogenide (ChG) glasses have the characteristics of a wide transparency window (over 20 μm) and high optical nonlinearity (up to 103 times greater than that of silica glasses), exhibiting great advantages over silica and other soft glasses in optical property at mid-infrared (MIR) wavelength range. These make them excellent candidates for MIR supercontinuum (SC) generation. Over the past decades, great progress has been made in MIR SC generation based on ChG fibers in terms of spectral extension and output power improvement. In this paper, we introduce briefly the properties of ChG glasses and fibers including transmission, nonlinearity, and dispersion, etc. Recent progress in MIR SC generation based on ChG fibers is reviewed from the perspective of pump schemes. We also present novel ChG fibers such as As-free, Te-based, and chalcohalide fibers, which have been explored and employed as nonlinear fibers to achieve broadband SC generation. Moreover, the potential applications of MIR SC sources based on ChG fibers are discussed.
