Paper Abstract

In the nonlinear optics regime, photonic devices that have topologically nontrivial photonic bandstructures are predicted to support a novel class of "topological solitons", which inherit exotic features of linear topological edge states such as unidirectional edge propagation. We present a detailed theoretical study of the conditions under which topological solitons can arise, and how they can be used to implement nonlinear optical isolators. Such isolators can achieve large isolation ratios, while being robust to lattice defects. Our results are based on theoretical analysis backed by numerical simulations of coupled-waveguide lattice and ring resonator lattice structures.
