Phase conjugation revisited

David C. Brown, Kotik K. Lee

Published Jan 1, 1986• 0 citations

Abstract

We have proved, by using nonlinear wave equation among three independent methods, that: complete correction of phase distortions due to an optical device (or a system of several optical devices) by phase conjugation is possible if and only if the device (or the system) which produces such phase distortion is gainless, lossless, and time‐order invariant. Effects of saturated gain, finite coherence, and system symmetry are also discussed briefly.

Optical distortion in phase conjugation in high-gain three-wave mixing

Frederic A. Hopf

Optical distortion of phase conjugates made in high-gain degenerate, optical parametric amplifiers (OPA) using three-wave mixing is discussed theoretically. The distortion is shown to be less severe than predicted by low-gain formulas. This result applied also to four-wave OPA’s in transmission configurations.

Phase-distortion suppression in nonlinear cavities with gain

Воронцов Михаил Александрович, К. V. Shishakov

Effective suppression of phase distortions, similar to the phenomenon of optical phase conjugation, can occur in passive nonlinear cavities. By controlling the wave front inside the cavity, one can alter the spatial characteristics of the output radiation to form light fields with various structures.

Phase conjugation of nonstationary optical signals

J. A. Tataronis, Bahaa E. A. Saleh

The generation of phase conjugated replicas of optical signals has been the subject of many theoretical and experimental studies. Phase conjugation of harmonic signals is a byproduct of certain nonlinear processes such as degenerate four- wave mixing and stimulated Brillouin scattering. Although conjugation of steady signals is well established, the possibility and the effectiveness of conjugating unsteady signals remain largely unexplored. When the envelope of an optical signal varies, new physical phenomena in the conjugation process arise. As previously shown,1 dispersion in the conjugation process distorts the phase conjugate replica of a pulsed signal. Distortion appears even if the response of the medium to the applied optical signal is instantaneous.

Phase effects in passive nonlinear resonators

Воронцов Михаил Александрович, К. V. Shishakov

New effects in passive nonlinear resonators are considered. It is shown that effective suppression of phase distortions in systems of this kind resembles phase conjugation. Control of the phase of a light wave inside such resonators can provide an active means for modifying the spatial characteristics of the output radiation by producing optical fields with the required structure.

Optical Phase Conjugation and Image Reconstruction.

Hui‐Tian Wang

We review the concept and generation methods of phase conjugate waves. They are particularly emphasizedon optical phase conjugation with the photorefractive effects. Applications of phase conjugation are describedand methods of distorted image reconstruction in one-way image transmission, using both phase conjugationand photorefractive incoherent-to-coherent conversion techniques, are highlighted.

Thermodynamic bound on the phase-conjugate correction of optical distortions

Y. B. Band, Donald F. Heller, Oded Kafri

We show that there is a limit to the maximum efficiency achievable for correcting optical distortion (beam healing) using phase conjugation. This limit is quantum thermodynamic and stems from the impossibility of reducing the beam entropy by a lossless retrace of the phase aberrator.
