Abstract
A new design of nano-fiber having all-normal and flat-top dispersion in As2Se3 chalcogenide glass has been reported for broadband supercontinuum spectra ranging from 1580 to 7090 nm. Such broadband spectra in mid-infrared region has been obtained using only 2 mm long nano-fiber with 50 fs laser pulses of 500 W peak power. Proposed nano-fiber has been optimized to obtain zero dispersion wavelength at 3800 nm.
