Localized States in Nonlinear Topological Photonics

Hosted By: Nonlinear Optics Technical Group

24 November 2021, 14:00 - 15:00 - Eastern Time (US & Canada) (UTC - 05:00)

Recently discovered topological phases of light provide novel opportunities for photonic devices robust against scattering losses and disorder. Combining these topological photonic structures with nonlinear effects will unlock advanced functionalities such as magnet-free nonreciprocity and active tunability. In this webinar hosted by the Nonlinear Optics Technical Group, Daria Smirnova from Australian National University will discuss recent developments in bridging the physics of topological phases with nonlinear optics. This will cover self-action effects leading to edge solitons and modulational instability in topological photonic lattices, as well light generation in nanophotonic topological cavities and metasurfaces.
