Electro-optic modulator (EOM) is an optical device in which a signal-controlled element displaying electro-optic effect is used to modulate a beam of light. The modulation may be imposed on the phase, frequency, amplitude, or polarization of the modulated beam. Modulation bandwidths extending into the gigahertz range are possible with the use of laser-controlled modulators.
