Electro–optics is a branch ofelectrical engineering,electronic engineering,materials science, andmaterial physics involving components,electronic devices such aslasers,laser diodes,LEDs,waveguides, etc. which operate by the propagation and interaction of light with various tailored materials. It is closely related tophotonics, the branch ofoptics that involves the application of the generation ofphotons. It is not only concerned with the "electro–optic effect", since it deals with the interaction between theelectromagnetic (optical) and theelectrical (electronic) states of materials.

Theelectro-optic effect is a change in the optical properties of an optically active material in response to changes in an electric field. This interaction usually results in a change in thebirefringence, and not simply the refractive index of the medium. In aKerr cell, the change in birefringence is proportional to the square of the electric field, and the material is usually a liquid. In aPockels cell, the change in birefringence varies linearly with the electric field, and the material is usually a crystal. Non-crystalline, solid electro-optical materials have generated interest because of their low cost of production. These organic, polymer-based materials are also known as organic EO material, plastic EO material, or polymer EO material. They consist of nonlinear opticalchromophores in a polymer lattice. The nonlinear optical chromophores can producePockels effect.
