The electro-optic effect is the change in the refractive index resulting from applications of a dc or low-frequency electric field.

An electro-optic effect is a change in the optical properties of a material in response to an electric field that varies slowly compared with the frequency of light.

Pockels effect (or linear electro-optic effect): change in the refractive index linearly proportional to the electric field.

Combined with the photoeffect and photoconductivity, the electro-optic effect gives rise to the photorefractive effect.

This leads to a change in the index of refraction due to the electro-optic effect.

For typical intensities, optical rectification is a second-order phenomenon (difference frequency mixing) which is based on the inverse process of the electro-optic effect.

The electro-optic effect is a change of the optical properties of a given material in response to an electric field.

He discovered the quadratic electro-optic effect, a change in the refractive index of a material in response to an electric field, now known as the Kerr effect.

Refractive modulators most often make use of an electro-optic effect.

The internal space charge field, via the electro-optic effect, causes the refractive index of the crystal to change in the regions where the field is strongest.
