PHOTONIC CRYSTAL AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a photonic crystal which has a crystal structure having optical rotating power like in the case of a right quartz crystal and a left quartz crystal as right-hand and left-hand symmetricalness is collapsed, is applicable as a linear polarizer and has photonic band gaps and the optical rotating power and a process for manufacturing the same. SOLUTION: This crystal is two-dimensionally arrayed with columnar bodies 12 continuously and helically connected with the same material portions constituted by helically forming at least two kinds of the material portions 12a and 12b varying in refractive indices on a substrate 11. This process is for manufacturing the photonic crystal which is two-dimensionally arrayed with the columnar bodies 12 continuously and helically connected with the same material portions constituted by helically forming at least two kinds of the material portions 12a and 12b varying in the refractive indices on the substrate 11. After a stage (A) of forming the first helical first stage portions 12s on the substrate 11 and two-dimensionally arraying the same, a stage (B) of alternately laminating at least two kinds of the material portions 12a and 12b varying in the refractive indices successively by the first helical one stage portion 12s each on the first helical one stage portions 12s is repetitively executed.
