Abstract
The switching dynamics of ultrashort pulse under the effects of
intrapulse stimulated Raman scattering (ISRS) and intermodal dispersion in a
nonlinear two-core photonic crystal fiber (PCF) coupler is investigated
theoretically. A general model is proposed that includes all the significant
linear and nonlinear effects. In particular, we demonstrate with numerical
examples how the interaction of ISRS and intermodal dispersion affects the
pulse shape.
