We designed and developed tapered suspended-core fibers of high-purityAs39Se61 glass for supercontinuum generation in the mid-IR with a standardfiber laser pump source at 2 ${\mu}$m. It was shown that microstructuringallows shifting a zero dispersion wavelength to the range shorter than 2${\mu}$m in the fiber waist with a core diameter of about 1 ${\mu}$m. In thiscase, supercontinuum generation in the 1-10 ${\mu}$m range was obtainednumerically with 150-fs 100-pJ pump pulses at 2 ${\mu}$m. We also performedexperiments on wavelength conversion of ultrashort optical pulses at 1.57${\mu}$m from Er: fiber laser system in the manufactured As-Se tapered fibers.The measured broadening spectra were in a good agreement with the onessimulated numerically.
