Abstract
A photonic crystal surface-emitting laser includes a substrate, an n-type cladding layer, an active layer, a photonic crystal structure, a p-type cladding layer, an n-type semiconductor layer and a meta-surface structure. The n-type cladding layer is disposed over the substrate. The active layer is disposed over the n-type cladding layer. The photonic crystal structure is disposed over the active layer. The p-type cladding layer is disposed over the photonic crystal structure. The n-type semiconductor layer is disposed over the p-type cladding layer. The meta-surface structure disposed on a surface of the n-type semiconductor layer away from the p-type cladding layer.
