2–10 μm mid-infrared supercontinuum generation in As2Se3 photonic crystal fiber

For the first time, we demonstrate that a hyper-broadband output from 2 to 10 μm can be generated with a high spectral flatness by using a ∼4 μm pump and an As2Se3 photonic crystal fiber. The broad and flat dispersion profile and the low guiding loss of the endlessly single-mode As2Se3 photonic crystal fibers, combined with the high nonlinearity and the wide mid-infrared transparent window of As2Se3 chalcogenide glass, are essential for this high performance mid-infrared laser source.
