1. A two dimensional photonic crystal surface emitting laser having a laminated structure in which an active layer and a photonic crystal layer having a structure of a photonic crystal are laminated on a substrate,having a resonance mode in an in-plane direction of the photonic crystal, and extracting light in a vertical direction to a surface of the photonic crystal, whereinthe laminated structure has a multi-refractive index layer including a central region made of a high refractive index medium and a peripheral portion made of a low refractive index medium with a lower refractive index than that of the high refractive index medium.
