Disclosed is a beam steering device capable of adjusting a reflection angle of incident light and reflecting the incident light to a desired location. Also disclosed is an optical apparatus configured to detect light reflected from an external object and to extract information with respect to the external object. The beam steering device includes: a substrate; an antenna layer disposed on the substrate; a dielectric layer covering the antenna layer; a refractive index changing layer disposed on the dielectric layer; and an electrode layer disposed on the refractive index changing layer.
