摘要
A spatial light modulator may include a refraction layer including first and second regions with refractive indices different from each other; and/or a metal thin film on a lower face of the refraction layer configured to generate surface plasmons due to light incident on the metal thin film via the refraction layer. When first light is incident on the refraction layer, a phase difference between light reflected by the first and second regions may occur. A spatial light modulator may include a metal thin film and a refraction layer on the metal thin film. The refraction layer may include a first region with a first refractive index and a second region with a second refractive index different from the first refractive index. When first light is incident on the refraction layer, there may be a phase difference between light reflected from the first and second regions.
