Abstract
A solid-state displacement element includes an inorganic layered compound having a layered structure and an organic substance inserted between layers of the inorganic layered compound. The solid-state displacement element expands or contracts in the lamination direction of the inorganic layered compound when irradiated with controlling light. An optical element and an interference filter using the same principle of expansion or contraction as that in the solid-state displacement element are also disclosed.

- 1. A solid-state displacement element comprising an inorganic layered compound having a plurality of inorganic layers and an organic substance intercalated between the inorganic layers, wherein the solid-state displacement element expands or contracts in the lamination direction of the inorganic layered compound when irradiated with controlling light.
- 12. An optical element comprising an inorganic layered compound having a plurality of inorganic layers and an organic substance intercalated between the inorganic layers, wherein when controlling light is applied to the optical element, the optical element expands or contracts in the lamination direction of the inorganic layered compound, thus modulating the polarization of transmitted light passing through the optical element.

19. An interference filter for transmitting or reflecting light in a predetermined wavelength region, the interference filter comprising a multilayered film comprising a dielectric material and a solid-state displacement thin film disposed between layers of the multilayered film,
wherein the solid-state displacement thin film comprises an inorganic layered compound having a plurality of inorganic layers and an organic substance intercalated between the inorganic layers; - and
when controlling light is applied to the interference filter, the solid-state displacement thin film expands or contracts in the lamination direction of the inorganic layered compound, and a dielectric constant tensor thereof changes, and thus the wavelength region of light passing through or reflected from the interference filter changes. - View Dependent Claims (20, 21, 22, 23, 24)
