Second-harmonic generation based on double higher-order topological corner states
Topological corner state provides a promising platform for enhancing nonlinear optical effects, since it enables the light highly localized and is topologically protected against defects. Here, we realize second-harmonic generation (SHG) based on the nonlinear interactions between two different type...
