Abstract

Lately, there has been a renewed attention to the study of multimode signals and their ultrafast interactions. One fascinating phenomenon in this field is known as nonlinear multimode dispersive waves. These waves are frequently observed and hold significant applications across diverse physical systems. While the single-mode case of these waves has been widely researched, the multimode scenario remains relatively unexplored. Understanding and studying nonlinear multimode dispersive waves holds great significance in predicting and analyzing wave phenomena within many systems. In our lab, we developed multimode time lens, which can measure the temporal and spatial dynamics of signals inside multimode fibers. We study the interactions of multimode dispersive waves, in both frequency and time domain. We use the multimode time lens we developed to image and analyze the temporal dynamics between the different spatial modes, as well as the modes coupling over time and the energy transfer between them. In this talk, we will present our measurement system in details and describe our novel results on multimode dispersive waves interactions.
