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.

A photonic crystal surface-emitting laser, comprising:
- a substrate;
- an n-type cladding layer disposed over the substrate;
- an active layer disposed over the n-type cladding layer;
- a photonic crystal structure disposed over the active layer;
- a p-type cladding layer disposed over the photonic crystal structure;
- a first n-type semiconductor layer disposed over the p-type cladding layer;
- and
- a meta-surface structure disposed on a surface of the first n-type semiconductor layer away from the p-type cladding layer, wherein the meta-surface structure is an additional layer attached to and in contact with the surface of the first n-type semiconductor layer away from the p-type cladding layer.
