title: Nonlinear pulse dynamics in multimode silicon core optical fibers.
abstract: Multimode propagation in silicon core optical fibers is investigated via numerical modeling of the coupled mode equations. The simulations consider spectral evolution in two fibers with different micrometer-sized cores that have experimentally been shown to exhibit nonlinear broadening. The results indicate that most of the coupled power is propagated in the fundamental mode of each fiber, with a small contribution from the higher-order modes affecting the spectral shape but not the width of the broadening.
