A two-dimensional photonic crystal surface emitting laser includes an n-doped substrate, an n-doped cladding layer, an active layer, a photonic crystal layer, a p-doped cladding layer and a p-doped contact layer arranged in sequence from top to bottom. The photonic crystal layer includes a base material and a plurality of unit cells arranged periodically, each unit cell includes a first different-refractive index region, a second different-refractive index region and a third different-refractive index region that have a different refractive index from the base material. The surface emitting laser based on the photonic crystal structure may maintain single-mode operating characteristics of a device under a large mode field area, so that a high-power single-mode surface emitting laser may be achieved.
