<p><P>PROBLEM TO BE SOLVED: To provide a method for controlling the refractive index of a periodical structure to arbitrarily control the non-periodical property of the refractive index, to provide a periodical structure in which the non-periodical property of the refractive index can be arbitrarily controlled, and to provide an optical element by using the above periodical structure in which not only changes in the refractive index can be arbitrarily controlled but the changes in the refractive index can be maintained and reversibly eliminated. <P>SOLUTION: The method for controlling the refractive index of a periodical structure 6 prepared by periodically arranging an optical medium in or on an optical base material 1 includes a process of applying a magnetic field on the periodical structure 6. <P>COPYRIGHT: (C)2003,JPO</p> |
