Distortion correction by phase conjugation of nonparaxial vectorial beams: a general proof.
نویسندگان
چکیده
We present a general proof of the distortion-correction theorem, that is, of the possibility of correcting wave distortion by the technique of optical phase conjugation. The proof is valid for fully vectorial nonparaxial propagation in the presence of a tensorial refractive-index perturbation and backscattering of the incident field.

Compensation for phase distortions in nonlinear media by phase conjugation.
The ability of nonlinear optical phase-conjugate mirrors (PCM's) to correct for linear refractive-index inhomogeneities has been demonstrated both theoretically1'2 and experimentally.2 Propagation media often possess intensity-dependent indices of refraction that cause severe propagation distortion, such as thermal blooming and self-focusing. These distortions are often manifested in high-inten...
متن کاملSpecial Issue Papers Polarization and Spatial Information Recovery by Modal Dispersal and Phase Conjugation: Properties and Applications
We describe recent theoretical and experimental studies of polarization and spatial information recovery by modal dispersal and phase conjugation. We discuss the fidelity of this phase-conjugation process as a function of input-beam launching conditions. We also describe several new applications of the scheme which involve correction of nonreciprocal polarization distortions, correction of loss...
متن کاملFully vectorial accelerating diffraction-free Helmholtz beams.
We show that new families of diffraction-free nonparaxial accelerating optical beams can be generated by considering the symmetries of the underlying vectorial Helmholtz equation. Both two-dimensional transverse electric and magnetic accelerating wave fronts are possible, capable of moving along elliptic trajectories. Experimental results corroborate these predictions when these waves are launc...
متن کاملClosed-form expressions for nonparaxial accelerating beams with pre-engineered trajectories.
In this Letter, we propose a general real-space method for the generation of nonparaxial accelerating beams with arbitrary predefined convex trajectories. Our results lead to closed-form expressions for the required phase at the input plane. We present such closed-form results for a variety of caustic curves: beside circular, elliptic, and parabolic, we find for the first time general power-law...
متن کاملRelativistic electron vortex beams: angular momentum and spin-orbit interaction.
Motivated by the recent discovery of electron vortex beams carrying orbital angular momentum (AM), we construct exact Bessel-beam solutions of the Dirac equation. They describe relativistic and nonparaxial corrections to the scalar electron beams. We describe the spin and orbital AM of the electron with Berry-phase corrections and predict the intrinsic spin-orbit coupling in free space. This ca...
