Polarization vector
Now consider a uniformly polarized slab in which the polarization density vector lies in the plane of the slab as shown in Figure (2.7.12). In this case the polarization has only an x-component, and that x-component, P x, is a function only of z.Phase conjugation of vector vortex beams has also been realized in photorefractive crystals, 148,149 demonstrating the “healing” of polarization defects, as well as in stimulated parametric downconversion. 150 The latter provides a convenient approach of generating a conjugate vector beam from a vectorial probe used as a seed in real time ...

Polarization refers to the direction of travel of an electromagnetic wave vector’s tip: vertical (up and down), horizontal (left to right), or circular (rotating in a constant plane left or right). The direction of polarization is defined by the orientation of the wave’s electric field, which is always 90°, or perpendicular, to its ... In addition, there exist several states of elliptically polarized light that lie between linear and non-polarized, in which the electric field vector transcribes the shape of an ellipse in all planes perpendicular to the direction of light wave propagation. Elliptical polarization, unlike plane-polarized and non-polarized light, has a ...Up t o and including Equation (\(\ref{A15}\)) (page 8) we shall assume that the polarization is total.
