Abstract
A phase modulation device includes an upper reflective layer onto which incident light is incident; a lower reflective layer provided on a lower portion of the upper reflective layer; an active layer provided between the upper reflective layer and the lower reflective layer; a first electrode connected to an upper surface of the active layer; and a second electrode connected to a lower surface of the active layer, wherein the lower reflective layer may include a first distributed Bragg reflector (DBR) layer including at least one first low refractive material layer and at least one first high refractive material layer that are alternately stacked, and the at least one first low refractive material layer has a first refractive index and the at least one first high refractive material layer has a second refractive index that is greater than the first refractive index.
