Abstract In this work, we extend temporal reflection and refraction analogies from the case of singlemode optical fibers to multimode fibers. Specifically, show that nonlinear provide novel degrees freedom permit us control pulse interactions. We take advantage properties pulses propagating in different modes, such as their group velocities, dispersion parameters, effective mode areas, presence Kerr effect. Our study was carried out by numerically solving Schrödinger equations for graded-index From analysis, find a useful tool obtain all-optical switching frequency conversion schemes
