An international team of researchers has investigated the interplay of topology and non-Hermitian physics with nonlinear effects. In their paper published in the journal Science, the group describes contructing an optical waveguide lattice using a biased photorefractive crystal and experiments introducing nonlinear effects. Piotr Roztocki and Roberto Morandotti with INRS-Énergie, Matériaux et Télécommunications have published a Perspective piece in the same journal issue outlining the benefits of studying nonlinear systems and work by the team on this new effort.
