An electro–optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an 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 beam. EOMs are widely used in telecommunications, laser systems, and scientific research due to their ability to precisely. Our Free-space Electro-optic modulators (EOMs) are efficient, convenient and easy to use tools to modify the phase, frequency, polarization or amplitude of a free-space laser. EOMs achieve this by precisely controlling a property of the.
