Optical modulators are devices allowing one to manipulate properties of light beams, such as the optical power or phase, according to some input signal.
According to the properties of the material that are used to modulate the light beam, modulators are divided into two groups: absorptive modulators and refractive modulators. In absorptive modulators the absorption coefficient of the material is changed, in refractive modulators the refractive index of the material is changed. The absorption coefficient of the material in the modulator can be manipulated by the Franz–Keldysh effect
Optical modulators use electrical signals to modify the physical characteristics of materials in such a way that the propagation conditions of light change. This
