Abstract
Unidirectional wave propagation in nonreciprocal structures enables exciting opportunities to control and enhance light-matter interactions in extreme ways. In this talk, we present our recent efforts on this exciting topic with particular focus on nonreciprocal plasmonic structures. We theoretically demonstrate remarkable levels of field enhancement and confinement when a plasmonic waveguiding structure supporting one-way modes is suitably terminated. We show that this effect leads to a substantial boosting of nonlinear light-matter interactions, exemplified by an improvement of several orders of magnitude in the third-harmonic-generation efficiency. We also discuss our recent work on nonreciprocal nonmagnetic thermal radiation effects in plasmonic systems.
