In this talk, we will discuss our recent efforts on nonlinearity-based wave interactions in metamaterials, including large isolation and non-reciprocal responses, giant harmonic generation, and nonlinearity-induced topological protection in suitably designed metamaterials. The large wave-matter interactions in metamaterials can be tailored to enhance the typically weak nonlinearities of optical materials to realize new devices and systems with unusual functionalities, of interest in nanophotonics, optical communications and sensing.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
