Abstract
An optical field enhancement device which includes a transparent substrate having a transparent fine uneven structure on a surface and a metal film formed on a surface of the fine uneven structure on the surface of the substrate and allows projection of excitation light and detection of detection light either from a front surface side of the metal film or from a back surface side of the transparent substrate.
Claims8
An optical field enhancement device, comprising a transparent substrate having a transparent fine uneven structure on a surface and a metal film formed on a surface of the transparent fine uneven structure on the surface of the substrate,
- wherein the device is configured such that an enhanced optical field is created on a surface of the metal film by an optical field enhancement effect of localized plasmon induced on the surface of the metal film by light projected onto the fine uneven structure on which the metal film is formed.
