PHOTONIC CRYSTAL ELEMENT, SPECTRAL SYSTEM HAVING THE SAME, DETECTION KIT AND DETECTION SYSTEM FOR DETECTION TARGET MATERIAL, AND METHOD FOR MANUFACTURING PHOTONIC CRYSTAL ELEMENT

摘要

To provide a photonic crystal element capable of dispersing visible light at low price.SOLUTION: A spectral element 11 includes: a substrate 110; a metal thin film 111 which is on the substrate 110 and is made of pure metal; and a polymer layer 112 which is formed of a resin transmitting visible right and is on the metal thin film 111. The polymer layer 112 is provided with holes P at regular intervals with diameters smaller than the wavelength of visible light. The polymer layer 112 has a dot-like defect region R2 in which a part of the holes P are missing as dots.SELECTED DRAWING: Figure 14
