Patent ID: 7308181

Claim:
A method for manufacturing a three-dimensional photonic crystal including a stacked plurality of layers, comprising: a step of controlling the thickness of the layers; a step of forming periodic refractive index structures in the layers; and in a case of an error in the thickness of each layer or dimensions of each periodic refractive index structure, a step of adjusting the thickness of each layer or dimensions of each periodic refractive index structure such that the layer satisfies the following equation: ( n eff+Δ n eff)×( H×ΔH )× M=n eff× H wherein H represents the design thickness of the layer, neff represents the design effective refractive index of the periodic refractive index structure, Δneff represents a deviation of the effective refractive index of the periodic refractive index structure from the design effective refractive index, ΔH represents a deviation of the thickness of the layer from the design thickness, and M represents a coefficient between 0.5 and 2.0.
