Abstract:

Multimode optics holds a great promise for several applications ranging from broadband communication systems to the implementation of high-power lasers. For instance, due to their multifaceted optical response, multimode optical fibers are expected to play a prominent role in the future quantum internet, where hyper-dimensional light states will allow for the efficient encoding and distribution of massive amounts of information at very high speed. Simultaneously, in the strong-field regime, multimode optical systems may exhibit optical nonlinearities that give rise to intermodal energy exchange, which is the starting point in a variety of intriguing phenomena having countless applications. Examples include high-harmonic and supercontinuum generation, parametric instabilities, modal condensation, and beam self-cleaning effects. In this talk, I will give you an overview of the topic of thermalization in multimode nonlinear optical systems, as well as present to you a numerical analysis of thermalization in chosen discrete and continuous nonlinear multimode optical systems.
