Abstract

Group velocity matching is a key to the performance of multimode microstructure fibers. Simulations show that only partial matching is achieved using an intuitive graded-hole strategy, but that the usual velocity-matching limit can be achieved by numerically optimizing designs. These results demonstrate the perturbative multipole numerical method and are a step toward improved strategies for achieving high-performance microstructure fibers for a multimode transmission.
