Electro optic effect

The 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. The term encompasses a number of distinct phenomena, which can be subdivided intoa) change of the absorptionelectroabsorption: general change of the absorption constantsFranz-Keldysh effect: change in the absorption shown in some bulk semiconductorsQuantum-confined Stark effect: change in the absorption in some semiconductor quantum wellselectro-chromatic effect: creation of an absorption band at some wavelengths, which gives rise to a change in colour

Any one of a number of phenomena that occur when an electromagnetic wave in the optical spectrum interacts with an electric field, or with matter under the influence of an electric field. (188 ) Note 1: Two of the most important electro-optic effects having application as modulation mechanisms in optical communication are the Kerr effect and the Pockels effect, in which birefringence is induced or modified in a liquid (Kerr effect) or solid (Pockels effect). Note 2: The term "electro-optic" is often erroneously used as a synonym for "optoelectronic."
