Optical Modulation
Optical modulation refers to the process of varying the optical power levels to represent digital information, characterized by the Optical Modulation Amplitude (OMA), which is defined as the
Optical Modulation (Chapter 10)
Optical modulation can be categorized as direct modulation or external modulation. Direct modulation is directly performed on an optical source, which is usually a
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
