Demonstration of amplitude-distortion correction by modal dispersal and phase conjugation.

چکیده
We demonstrate experimentally and explain theoretically polarization-preserving imaging through a lossy amplitude-distorting medium. This is accomplished by propagating the beam, before its arrival at the lossy distorting medium, through a (multi) mode- and polarization-scrambling fiber and reflecting the signal, after it has passed the lossy distorting medium, from a photorefractive phase-conjugate mirror.

Special 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 کاملOptical phase-conjugate correction for propagation distortion in nonreciprocal media.
We demonstrate experimentally that the effects of nonreciprocal elements or media that would otherwise spoil phase conjugation can be neutralized by using a tandem combination of a modal- and polarization-scrambling fiber and a phase-conjugate mirror. A theoretical model to explain the experimental results is presented.
متن کاملTheory of polarization and spatial information recovery by modal dispersal and phase conjugation
A general theory of polarization and spatial information recovery by modal dispersal and phase conjugation is presented by means of a coherency matrix formalism. The theory is applied to a system that consists of a multimode modal-scrambling fiber terminated by a conventional phase-conjugate mirror that reflects only one polarization component. The degree of polarization and the signal-to-noise...
متن کاملTheoretical model for modal dispersal of polarization information and its recovery by phase conjugation.
A theoretical model is proposed for explaining the recently observed modal dispersal of polarization information and its recovery in an experiment in which the coupling dispersing fiber. to the phase conjugator is by means of a (multi)mode dispersing fiber.
متن کاملDistortion correction by phase conjugation of nonparaxial vectorial beams: a general proof.
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.
