PROBLEM TO BE SOLVED: To provide a technique to fabricate a periodical structure having different optical characteristics in specified parts, that is, a periodical structure with patterned characteristics. SOLUTION: A photonic crystal having a part, where a photonic band gap is formed by the inverse structure of a periodical structure of a substance in the almost same shape, is equipped with both of a part (gap 2) having an inverse structure region and a part, where another substance (packing material 3) filling the gap in the inverse structure is present, on a substrate 4. The method for fabricating the above structure includes: a step (a) of forming a region (gap 2) having a part where a photonic band gap is formed by the inverse structure of a periodical structure of a substance in the almost same shape; and a step (b) of dropping a colloid solution containing fine particles larger than the periodical interval of the periodical structure in the step (a) onto a specified part while controlling the drop amount, and vaporizing a solvent in the colloid solution to form an aggregate (packing material 3) of fine particles in the gap. The numeral 1 represents a packing material. COPYRIGHT: (C)2007,JPO&INPIT |
