PROBLEM TO BE SOLVED: To provide a method for easily producing a periodic index structure having a period nearly equal to light wavelength and usable as a defect-free or defective photonic structure. SOLUTION: A suspension of spherical particles 5 having a size nearly equal to light wavelength and uniform in diameter is dropped on a substrate 1 with receiving parts 3, 4 and the particles 5 are aggregated in the receiving parts 3, 4 by applying load 6 to the particles 5 to produce a photonic structure. Since the load 6 is applied to the suspension, the spherical particles can be close- packed in the receiving parts 3, 4 and the objective periodic index structure usable as a one-, two- or three-dimensional photonic structure is formed. |
