The so-called optical modulation technology is a modulation technology in which a signal carrying information is superimposed on the carrier light wave. Laser modulation technology can be divided into amplitude modulation, phase modulation, frequency modulation, polarization modulation and so on. According to modulation methods, it can be divided into acousto-optic modulation, electro-optic modulation, magneto-optical modulation and so on.
