Nonlinear dynamics in complex optical systems
In recent years, the complex nonlinear response of optical systems, such as strong competing nonlocal interactions in soft matter or weakly nonlinear highly multimode topological and trivial arrangements, has attracted considerable attention. To a great extent, what has motivated this interest is a quest for robust all-optical switching and high-power optical sources that has been enabled by a sequence of new developments in multimode technologies on both guided-wave structures and photonic cavities. However, as lately indicated in a number of studies, the action of nonlinearity, including the interplay of nonlinearity and topology in photonic configurations, can lead to a host of novel effects that have never been observed before. In this talk, several of our recent results will be presented concerning a topologically protected light transport, a new class of solitons arising from nonlocal interactions, and a new optical thermodynamic framework suited for highly complex nonlinear multimode systems.
