Abstract: Optical refraction and reflection control can be achieved by means of semiconductor silicon which has a p-n junction structure and a waveguide structure. According to the optical device using semiconductors of the present invention, the amplitude of light can be directly modulated using the reflection or refraction control. The optical device according to the preferred embodiment of the present invention includes: a first waveguide on which an optical signal is incident, and which is formed in the same direction as that of the incident optical signal; a second waveguide that forms a fixed angle with the first waveguide; and a reflector which is capable of selecting a path of the optical signal to the first waveguide or to the second waveguide as a refractive index is changed according to an applied voltage, and which is formed to have a fixed angle of inclination with respect to the first waveguide.
