Optical modulator

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
