# Observation of Floquet solitons in a topological bandgap

@article{Mukherjee2020ObservationOF, title={Observation of Floquet solitons in a topological bandgap}, author={Sebabrata Mukherjee and Mikael C. Rechtsman}, journal={Science}, year={2020}, volume={368}, pages={856 - 859} }

Topological insulators go nonlinear Whereas solid-state insulators tend to be fixed by material properties, photonic topological insulators can be designed at will to mimic a variety of scenarios and complex interactions. Mukherjee and Rechtsman go beyond the linear optical regime that has been studied to date and show that photonic topological insulators can also exhibit nonlinear optical features (see the Perspective by Ablowitz and Cole). Their array of laser-written waveguides can support…
