Design of a mid-wave IR (MWIR) broad-band fiber-based light source exploitingfour-wave mixing (FWM) in a meter long suitably designed highly nonlinear (NL)chalcogenide microstructured optical fiber (MOF) is reported. This superior FWMbandwidth (BW) was obtained through precise tailoring of the fibers dispersionprofile so as to realize positive quartic dispersion at the pump wavelength. Weconsider an Erbium (Er3+) doped continuous wave (CW) ZBLAN fiber laser emittingat 2.8 micron as the pump source with an average power of 5 W. Amplificationfactor as high as 25 dB is achievable in the 3 to 3.9 microns spectral rangewith average power conversion efficiency more than 32 percent.
