Three-dimensional periodic structure and method for producing the same

摘要

Photonic crystal units ( 10 a , 10 b, and 10 c) are formed by an optical molding process using a photocurable resin, and partitions ( 11 ) are provided at the boundaries therebetween. The voids in each photonic crystal unit are filled with a second substance containing ceramic particles dispersed therein to form a filled portion 2 . A plurality of three-dimensional periodic structure units containing the first and second substances distributed with three-dimensional periodicity are arranged so as to have different ratios between the dielectric constants of the first and second substances. Therefore, present invention provides a three-dimensional periodic structure having a wide photonic band gap which could not be obtained in a conventional three-dimensional periodic structure.
