Electro-optics

Electro-optics

Electro-optics is a branch of technology involving components, devices and systems which operate by modification of the optical properties of a material by an electric field. Thus it concerns the interaction between the electromagnetic (optical) and the electrical (electronic) states of materials.

Electro-optical devices

The electro-optic effect relates to a change in the optical properties of the medium which usually is a change in the birefringence and not simply the refractive index.In a Kerr cell, the change in birefringence is proportional to the square of the electric field, and the material is usually a liquid.

In a Pockels cell, the change in birefringence varies linearly with the electric field, and the material is a crystal.

Terminology

"Electro-optic" is often erroneously used as a synonym for "optoelectronic".
