An '''optical modulator''' is a optical device which is used to modulate a beam of light with perturbation device. it is a kind of transmitter to convert information to optical binary signal through [[optical fiber]] ([[optical waveguide]]) or transmission medium of optical frequency in fiber optic communication. There are several method to manipulate this device depending on the parameter of a light beam like [[amplitude modulator]] (majority), [[phase modulator]], polarization modulator etc.
