It is essentially the same as what is popularly described today as [[photonics]]. It is not only concerned with the &quot;[[electro–optic effect]]&quot;. Thus it concerns the interaction between the [[electromagnetism|electromagnetic]] ([[optics|optical]]) and the [[electricity|electrical]] ([[electron]]ic) states of materials.<br /> <br /> == Electro-optical devices ==<br /> The [[electro-optic effect]] is a change in the optical properties of an optically active material due to interaction with light. This interaction usually results in a change in the [[birefringence]], and not simply the refractive index of the medium. In a [[Kerr cell]], the change in birefringence is proportional to the square of the optical 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 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 optical [[chromophores]] in a polymer lattice. The nonlinear optical chromophores can produce [[Pockels effect]].<br /> <br /> ==References==<br /> *{{FS1037C MS188}}<br /> *{{DODDIC}}<br /> * {{cite book<br /> | last = Friedman<br /> | first = Edward<br /> | title = Photonics Rules of Thumb: Optics, Electro-optics, Fiber Optics, and Lasers<br /> | publisher = McGraw-Hill Professional<br /> | year = 2004<br /> | isbn = 0-07-138519-3 }}<br /> <br /> ==External links==<br /> * [http://www.unmannedsystemstechnology.com/category/supplier-directory/cameras-imaging-systems/electro-optical-systems/#intro Introduction to Electro-Optical Systems in Unmanned Vehicle Applications - Unmanned Systems Technology]<br /> <br /> {{Authority control}}<br /> <br /> [[Category:Atomic, molecular, and optical physics]]<br /> [[Category:Optoelectronics]]<br /> [[Category:Nonlinear optics]]</div>
