Noun
Kerr effect
(physics) Birefringence of a material induced by an electric field due to partial orientation of its molecules.
However, there is also the non-linear Kerr effect : the refractive index of a material at a given frequency depends on the light's amplitude or strength. Source: Internet
If the pulse has just the right shape, the Kerr effect will exactly cancel the dispersion effect, and the pulse's shape will not change over time: a soliton. Source: Internet
Only certain crystalline solids show the Pockels effect, as it requires lack of inversion symmetry ** Kerr effect (or quadratic electro-optic effect, QEO effect): change in the refractive index proportional to the square of the electric field. Source: Internet
The refractive index of materials can also be nonlinear, as occurs with the Kerr effect when high intensity light leads to a refractive index proportional to the intensity of the incident light. Source: Internet
The results of reflection from a magneto-optic material are known as the magneto-optic Kerr effect (not to be confused with the nonlinear Kerr effect ). Source: Internet
