The switching dynamics of short pulses propagating in a two-core optical fiber under the effects of intrapulse stimulated Raman scattering (ISRS) and intermodal dispersion is investigated theoretically. We find that, when the input pulses are short and intense enough, ISRS in general reduces the width of the pulses propagating in the launching core of the fiber and, at the same time, slows down the pulses. However, if the two-core fiber contains sufficient intermodal dispersion, the pulse-narrowing effect of ISRS can be weakened. Using typical fiber parameters, we demonstrate with numerical examples how the interaction of ISRS and intermodal dispersion affects the pulse shape. © Springer-Verlag 2007.
