A device that uses an electric signal to change a light beam's brightness or timing
  • noun
  • Specialized
translation icon : EOM
  • In the lab, the physicist used an EOM to control the intensity of the light during the experiment.

Examples

  • The engineer adjusted the settings on the EOM to improve the signal quality of the laser beam.

  • The VCO source can be manually tuned over one octave (typically), or the VCO frequency can be set to track the resonant peak of the EOM.

    Academic text (2003)

  • To achieve precise modulation, the technician implemented the EOM in the optical circuit design.

Morphology

EOM = E + O + M

A technical initialism for 'electro-optic modulator' whose meaning relies on specialised technical terms rather than on transparent English morphemes, so knowing the letters does not let a general learner derive the meaning.

Etymology

EOM comes from the technical phrase electro- 'electric', optic 'light', and modulator 'something that changes', so it literally names a device that uses electricity to change light. This is why an EOM is used to control the phase or intensity of a light beam.
