The generated SC covers two octaves of bandwidth from 1.1 µm to 4.4 µm at -30 dB. This exceeds the broadest reported SC bandwidth in As2Se3 microwires by a factor of 3.5. The microwire geometry and pumping conditions are the key parameters in generating the 3.3 µm bandwidth while using a low pump pulse energy of 500 pJ.31131-31137engArtigo10.1364/OE.22.031131Acesso restrito2998503841917815
