Abstract
By using an As2Se3 based holey fiber (HF) with a normal flat dispersion profiles, a flattened and broadband mid-infrared super-continuum generation is analysed. The transmission of an ultra-short pulse in the HF is numerically simulated by solving the generalized nonlinear Schrödinger equation under various parameters. The simulation results show that, by launching a pulse with a width of 50 fs and a peak power of 4.25 kW at 4375 nm into the 6 mm-long HF, a flat and broadband super-continuum at 3 dB level is successfully generated. The super-continuum covers the wavelengths from 3866 to 5958 nm which is the largest flat bandwidth reported in such a short fiber.
