In this study, we propose to construct topological photonic crystal resonant cavities in both horizontal and vertical directions simultaneously to obtain low-threshold and high-robustness novel lasers that provide topological protection in both directions. In the vertical direction, we designed resonant cavities based on one-dimensional topological photonic crystals: the supported longitudinal topological protection mode realizes the Zak phase flip on the topological boundaries, which creates an effective cavity feedback at the topological edge. In the horizontal direction, we designed a resonant cavity based on a two-dimensional topological photonic crystal, which realizes the light-field confinement effect via the flip between the topological state energy bands of the Γ-points and the energy bands of the tundish state. This not only confines the transverse modes supported by the cross-section of the laser to the inside of the topological photonic crystal but also allows the transverse modes to exhibit good anti-defect capability. The proposed topological photonic crystal laser offers the advantages of single mode and robustness, which is expected to further broaden the application of future lasers.
