Fourth order cascaded Raman shift in As38Se62 chalcogenide suspended core fiber pumped at 1.995 μm
2011
Fourth order cascaded Raman wavelength shift is demonstrated in As 38 Se 62 suspended core fiber using 1995 nm nanosecond source. The measured Raman gain coefficient is∼2×10−11 m/W at 1995 nm. The Raman peaks are reproduced by numerical simulations.
Mid-infrared strong spectral broadening in microstructured tapered chalcogenide AsSe fiber
2012
We report on the generation of a supercontinuum in a chalcogenide microstructured tapered fiber. The suspended core diameter of the fiber is reduced from 5.5 μm to 0.8 μm in the waist of the tapered region. The zero dispersion wavelength is below 2 μm in the tapered region. To pump the fiber, we use a modelocked laser of 4 ps, with a central wavelength of 1960 nm. With only 150 W peak power in the fiber a supercontinuum is generated from 1300 to 2600 nm taking the supercontinuum wavelength edge at -30 dB from the continuum.
