We analyze the stability and dynamics of dissipative Kerr solitons (DKSs) in the presence of a parabolic potential. This potential stabilizes oscillatory and chaotic regimes, favoring the generation of static DKSs. Furthermore, the potential induces the emergence of new dissipative Read More …

In spite of their ubiquitous applications, the characterization of glass fibers by meansof all-optical techniques is still facing some limitations. Recently, X-ray absorption has beenproposed as a method for visualizing the inner structure of both standard and microstructure opticalfibers. Here, Read More …

We introduce a numerical procedure which permits us to drastically accelerate the design of multimodephotonic crystal resonators. Specifically, we demonstrate that the optical response of an important class of suchnanoscale structures is reproduced accurately by a simple, one-dimensional model within Read More …

Multimode devices and components have attracted considerable attention in the last years, and different research topics and themes have emerged very recently. The multimodality can be seen as an additional degree of freedom in designing devices, thus allowing for the Read More …

Optical solitons in multimode fibers exhibit complex dynamics, and peculiar characteristics in terms of pulse durationand energy, which distinguish them from the single-mode counterpart. We propose a theory for Raman-induced soliton selffrequency shift in multimode fibers, that is compared against Read More …
