We use hybrid polymer-chalcogenide optical microwires to realize mid-infrared frequency conversion via the process of normal dispersion modulation instability (MI). Phase-matching is achieved through a negative fourth-order dispersion coefficient and leads to the apparition of parametric sidebands located at 2 μm and 3.5 μm, corresponding to a frequency shift of 30 Thz relative to the pump, which is among the largest reported using normal-dispersion pumped MI in a singlepass configuration in the mid-IR Stochastic nonlinear Schrödinger equation simulations are in excellent agreement with experiments.
