Abstract
A dispersive element comprises a substrate, a metal thin film made of pure metal and disposed on the substrate, and a polymer layer made of a resin that passes visible light and disposed on the metal thin film. A plurality of nanoholes each having a diameter smaller than the visible light's wavelength are periodically formed in the polymer layer. The polymer layer has a point defect in at least a portion of the plurality of nanoholes.

A photonic crystal device comprising:
- a substrate;
- a metal thin film made of pure metal and disposed on the substrate;
- and
- a resin layer made of a resin that passes visible light and disposed on the metal thin film,
- the resin layer having a plurality of nanoholes periodically formed therein and each having a diameter smaller than the visible light's wavelength,
- the resin layer having a point defect in at least a portion of the plurality of nanoholes.
A method for manufacturing a photonic crystal device, comprising:
- forming a metal thin film on a substrate;
- transferring a mold to a resin passing visible light to form a resin layer, the resin layer including a nanohole formation region and a point defect region, the nanohole formation region having a plurality of nanoholes periodically formed and each having a diameter smaller than the visible light's wavelength, the point defect region having some of the plurality of nanoholes with a point defect formed therein, the plurality of nanoholes each having an inverted tapered shape with a diameter increasing from the resin layer toward the metal thin film;
- bonding the resin layer and a provisional substrate together;
- removing the mold from the resin layer;
- bonding the metal thin film and the resin layer together;
- and
- removing the provisional substrate from the resin layer.
