Chalcogenide glass material has an ultra-broad infrared transmission window, ultrafast nonlinear response time and ultra-high third-order nonlinearity. The As₂S₃ material has lower cost, higher nonlinearity and a broader transmission span than other chalcogenide materials, which is a supporting factor for supercontinuum generation. In this paper, a chalcogenide As₂S₃ glass based Photonic Crystal Fiber (PCF) with an As₂S₃ glass fiber core and air-holes as the microstructure cladding was theoretically designed, and the optical performance of the As₂S₃ glass PCF was studied using a commercial software of COMSOL Multiphysics. The proposed As₂S₃ glass PCF preform was then experimentally fabricated using an improved molding method along with a chemical etching method. The As₂S₃ glass PCF was drawn at the temperature of 350^oC under the protection of dry N₂ gas. The fabricated As₂S₃ glass PCF has a solid hole in the center and its cladding consists of four layers of air holes arranged in regular hexagonal order. The solid core diameter of the fabricated As₂S₃ glass photonic crystal fiber is 10 μm, the diameter of the air-holes is 3.3 μm and the air hole pitch between the centers of proximal holes is 7.2 μm. For the fiber tapering process, a micro-tapering system using a CO₂ laser along with a scanning mirror and two high precision translation stages was established, all of which are computer programming controlled. The use of a CO₂ laser to heat the fiber is advantageous over standard oxyhydrogen flame-tapering systems since it allows greater control over the tapering parameters, namely the size of the irradiated zone over the sapphire capillary, the heating rate and the exposure time, and also this avoids potential further pollution of OH^- and H₂O into the As₂S₃ glass PCF. By mounting the As₂S₃ glass PCF on computer-controlled translation stages gives programmable dynamic control over the fiber tension, as well as the ability to control the position of the tapered section with an accuracy of ±0.5 μm. Using this tapering system, taper regions as long as 5 cm were achieved with a tapering fiber diameter reduction of 56%. The diameter of the As₂S₃ glass photonic crystal fiber can be tapered down to 40 μm based on the tapering method. To fabricate a pump source of supercontinuum generation, a customized mode-locked femtosecond (fs) fiber laser based on nonlinear polarization rotation effect in a home-made Ho³⁺/Pr³⁺ codoped (Ho³⁺∶2 mol.%, Pr³⁺∶0.2 mol.%) ZBLAN glass fiber (the core diameter is 12 μm, the cladding diameter is 125 μm and the NA is 0.16) was achieved and it generates 173 fs pulses at the wavelength of 2.87 μm with an estimated peak power of 25 kW and a repetition frequency of 42 MHz. Then, the tapered chalcogenide glass photonic crystal fibers were pumped using the above ZBLAN fs fiber laser to generate the mid-infrared supercontinuum spectra. After optimizing the tapered diameters of the tapered As₂S₃ glass photonic crystal fiber, the tapered As₂S₃ glass photonic crystal fiber with a waist diameter of 55 μm and a waist length of 3 cm can generate a supercontinuum spectral coverage range of 2 000 nm to 5 500 nm at the loss level of -20 dB. A theoretical model based on the well-known generalized non-linear Schr?dinger equation was also established for simulating the evolution of the proposed supercontinuum generation in the tapered As₂S₃ glass photonic crystal fiber over the length of 3 cm. The experimental results have a good agreement with the theoretically calculated results. This investigation constitutes a major step toward devoloping an efficient chalcogenide glass photonic crystal fiber based broadband supercontinuum light source operating in the mid-infrared region.
