Optical modulators are classified as active optical components because they require an external control signal—typically electrical, acoustic, or magnetic—to modify the properties of light, such as amplitude, phase, frequency, or polarization . Unlike passive components, which only guide or split light without altering its characteristics, active devices like modulators can encode information onto a light beam, enabling dynamic control in optical systems .
Optical modulators operate by exploiting material effects that respond to external stimuli:
