Abstract:
1. A two-dimensional photonic crystal laser, comprising: a two-dimensional photonic crystal layer having a base-body layer made of Al an epitaxial growth layer created over the two-dimensional photonic crystal layer by an epitaxial method; and a regrowth interface layer for epitaxially growing the epitaxial growth layer, the regrowth interface layer being disposed between the two-dimensional photonic crystal layer and the epitaxial growth layer, wherein: a material of the regrowth interface layer is composed of same elements as a material of the base-body layer of the two dimensional photonic crystal layer and a material of the epitaxial growth layer, while a content rate of Al and Ga of the regrowth interface layer is different from a content rate of Al and Ga of the base-body layer of the two-dimensional photonic crystal layer and the epitaxial growth layer; a material of the epitaxial growth layer is composed of same elements as the base-body layer of the two-dimensional photonic crystal layer while a content rate of each of the elements of the epitaxial growth layer is different from a content rate of each of the elements of the base-body layer of the two-dimensional photonic crystal layer; an Al content rate of the regrowth interface layer is higher than an Al content rate of the base-body layer of the two-dimensional photonic crystal layer; and the modified refractive index areas of the two-dimensional photonic crystal layer are air holes.
