Abstract
The effects of intermodal dispersion on ultrashort optical pulse
propagation through multi-core fibers are analyzed theoretically, which has
been ignored in previous studies. A three-core fiber with collinear and
triangular configuration and a four-core fiber are considered. We demonstrate
with numerical examples that the intermodal dispersion can cause pulse
breakup effect in multi-core fibers.
