Not to be confused with optoelectronics.

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[edit source | edit]

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. Non-crystalline electro-optic material have caught interested because of their low cost of production. It is polymer-based material, therefore is organic material. It is called sometimes as organic EO material, plastic EO material, or polymer EO material, which consists of a polymer and a nonlinear optical chromophore. Nonlinear optical chromophore is the molecule has Pockel's effect.

… A new scheme of electrooptic (EO) imaging, named detached EO imaging (DEI), has been proposed and demonstrated, where the finest imaging resolution for an electric field distribution over a planar circuit, which had been conventionally given by an EO sensor touching the circuit surface, has been provided by the EO sensor detached from the surface. …
