Mid-infrared supercontinuum generation in a novel AsSe2-As2S5 hybrid microstructured optical fiber

novel AsSe(2)-As(2)S(5) hybrid MOF (HMOF) is designed and fabricated by the rod-in-tube drawing technique. The core is made from AsSe2 glass and the cladding is made from As(2)S(5) glass. The loss is ~1.2 dB/m at ~3000 nm. Zero dispersion wavelength (ZDW) of the HMOF is ~3380 nm. Supercontinuum (SC) generation in a 2 cm-long HMOF is investigated with the pump wavelengths of ~3062, 3241 and 3389 nm from a tunable optical parametric oscillator (OPO) system. Broadband midinfrared (MIR) SC generation with the spectrum from ~1256 to 5400 nm is obtained with the peak power of ~1337 kW at the wavelength of ~3389 nm.
