Abstract
Provided is an optical body capable of arbitrarily and quickly controlling the optical characteristics of incident light. A refractive index variable layer () formed of PLZT or other material and a magneto-optical material layer () formed of garnet or other material are provided side by side between a first reflective layer () and a second reflective layer (). If linearly polarized light is made incident from the side of the first reflective layer (), the incident light interacts with the magneto-optical material layer () and is converted into a right-circularly polarized light component and a left-circularly polarized light component. A very small retardation occurring between both the right- and left-circularly polarized light components is amplified through multiple reflections between the pair of reflective layers () and is controlled according to a controlled refractive index of the refractive index variable layer ().
