Paper Abstract

We propose a chalcogenide (As2S3) core tellurite cladding microstructured fiber with flattened normal dispersion for ultraflat supercontinuum (SC) generation. To realize flattened normal dispersion, the structure parameters are optimized such as the chalcogenide core diameter, the air hole diameter and the distance between the centers of the two neighboring air holes. The ultraflat normal dispersion curve is obtained and the pulse propagation is investigated using a nonlinear Schrödinger equation. It is shown that an ultraflat SC spectrum with deviations less than 4 dB over an octave (from 1400 nm to 3000 nm) can be achieved by the illumination of a pulsed light with a pulse width of 200 fs, central wavelength of 2000 nm and peak power of 1000 W.
