Abstract

We predict that stable lasing in zero-dimensional corner states may occur in a second-order photonic topological insulator based on Kagome waveguide array with a rhombic configuration, under the balance between diffraction, focusing nonlinearity, uniform losses, two-photon absorption, and gain.
