Theory of polarization and spatial information recovery by modal dispersal and phase conjugation
نویسندگان
چکیده
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 ratio of the reconstructed field are discussed as a function of input-beam launching conditions. Some experimental results are also shown for comparison with the theory.

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 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 کاملDemonstration of amplitude-distortion correction by modal dispersal and phase conjugation.
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-conj...
متن کاملFocusing light through scattering media by full-polarization digital optical phase conjugation.
Digital optical phase conjugation (DOPC) is an emerging technique for focusing light through or within scattering media such as biological tissue. Since DOPC systems are based on time reversal, they benefit from collecting as much information about the scattered light as possible. However, existing DOPC techniques record and subsequently phase-conjugate the scattered light in only a single-pola...
متن کاملFidelity of polarization and spatial information recovery using a fiber-coupled phase-conjugate mirror.
We report the investigation of polarization and spatial information recovery using a fiber-coupled phase-conjugate mirror. A marked dependence of the phase-conjugate output on the input-beam conditions is experimentally observed. A theoretical model for these phenomena is also discussed.
