Nonlinear propagation in higher-order modes of microstructured optical fibers

Higher-order modes (HOMs) offer new opportunities for dispersion engineering in microstructured optical fibers (MOFs), while at the same time HOM properties may be engineered through MOF design. The peculiar modal properties of MOFs makes for interesting differences with step- or graded-index fibers. The talk will discuss simulation techniques for multimode nonlinear propagation in MOFs and show simulation examples of how HOM excitation can enable power scaling of ultrafast nonlinear processes in suitably designed MOFs.
