摘要
A light modulation element according to example embodiments includes a substrate; a first lower DBR layer on the substrate including a first material layer alternately stacked with a second material layer having a different refractive index from the first material layer; a second lower DBR layer on the first lower DBR layer with a surface area less than the first lower DBR layer and including a third material layer alternately stacked with a fourth material layer having a different refractive index from the third material layer; an active layer on the second lower DBR layer, including a semiconductor material having a multi-quantum well structure and having a refractive index that varies according to an applied voltage; and an upper DBR layer on the active layer including a fifth material layer alternately stacked with a sixth material layer having a different refractive index from the fifth material layer.
