OPTICAL ELEMENT AND ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2020/050008
Kind Code:
A1
Abstract:
[Problem] To provide an optical element and electronic equipment having a smaller size and lower profile as well as a higher response speed, and being capable of transmitted light intensity- or reflective light intensity-modulation at a high level.
[Solution] The optical element according to the present invention includes: a first optical reflective layer; a first thick-film dielectric layer; a multilayer laminate; a second thick-film dielectric layer; and a second optical reflective layer. The first thick-film dielectric layer is formed from a dielectric and is arranged on the first optical reflective layer. The multilayer laminate is arranged on the first thick-film dielectric layer and comprises a plurality of transparent conductive thin-films capable of controlling optical transition energy through Fermi level tuning and a dielectric thin-film that is a thin-film atomic layer arranged between the plurality of transparent conductive thin-films. The second thick-film dielectric layer is formed from a dielectric and is arranged on the multilayer laminate. The second optical reflective layer is arranged on the second thick-film dielectric layer.
