The combination of nonlinearity and topology has recently attracted significant attention in the field of optical physics. This work considers a photonic Chern insulator in the nonlinear regime and explores the properties of topological bulk solitons holding the stability and robustness, which contributes to the field of nonlinear topological photonics and provides further physical understandings towards other photonic topological insulators with nonlinearity.
