In this paper, we propose a design of a high numerical aperture multimode hybrid step-index fiber for mid-infrared (mid-
IR) supercontinuum generation (SCG) where two chalcogenide glass compositions As40Se60 and Ge10As23.4Se66.6 for the
core and the cladding are selected, respectively. Aiming to get accurate modeling of the SCG by the fundamental mode,
we solve the multimode generalized nonlinear Schrödinger equations and demonstrate nonlinear coupling and energy
transfer between high order modes. The proposed study points out the impact of nonlinear mode coupling that should be
taken into account in order to successfully predict the mid-infrared supercontinuum generation in highly nonlinear
