Abstract

A theory for a phase-conjugate bandpass filter based on multiwave-mixing effects in a thin Kerr medium is presented. As a result of the presence of side diffractions, several new features are observed in the power reflectivity, the bandpass, and the central frequency. Aside from a strong dependence on the wave-mixing angle, it is shown that components of different frequencies are generated at different reflected angles; at small input angles the filter can have a wide frequency bandpass with amplified output, and the central frequency is equal to the pump frequency regardless of the ratio of the pump beams.

Recent experimental observation of large probe beam gain at moderate laser power in a Kerrlike nonlinear medium demonstrated the possibility of constructing a self-pump ring oscillator and phase conjugator. We present a detailed theory, based on experimental parameters, of the working principles of such multiwave mixing mediated devices. The theory accounts for the side diffractions, which are responsible for probe beam gain in a Kerrlike medium, and other relevant parameters such as noise, loss, phase modulation, intensity dependences, etc.

Effects of side diffraction and phase modulation on optical multiwave mixing and phase conjugation

We report several recently observed optical wave mixing effects in thin films of nonlinear materials, such as liquid crystals and silicon. Kerrlike local and nonlocal and diffusive nonlinear resonses are studied. The presence of the diffracted beam is, theoretically and experimentally, shown to have a pronounced effect on the amplification of the probe beam in pump–probe wave mixing. The diffracted beam also drastically alters the phase conjugation reflection of the probe beam, phase conjugation self-oscillation threshold, and aberration correction characteristics.

Theory and experiments on stationary degenerate and nearly degenerate optical wave mixing and ring oscillation in a Kerr-like medium

Further theoretical observations and a new analysis of stationary degenerate and nearly degenerate optical wave mixing effects in a Kerr-like nonlinear medium are presented. The effects of phase modulations, beam ratio, intensity, wave mixing angle and frequency differences and other physical and optical parameters in multiwave mixing mediated probe gain and their application in ring oscillation devices are analyzed in detail. New experimental studies of the intensity and the angular dependence of the probe beam amplification and side diffractions in liquid crystal provide further insights into the phenomena.

Effects of side diffractions and phase modulations on phase conjugation in a Kerr medium

I. C. Khoo, W. Wang

The effects of side diffractions, generated from the interaction of a weak probe beam and its phase conjugate with two strong counterpropagating pump waves, and the effect of various intensity-dependent self- and mutual-phase modulations on the intensities of the probe beam and its phase conjugate are analytically studied in the nonpump-depletion limit. The results show that the conditions for the existence of, and threshold pump intensity parameters for, the divergence in the intensities of the probe and other generated beams are highly dependent on the wave-mixing angles and are different from the usual four-wave mixing phase conjugation process where the diffractions are not taken into account.>

Probe beam amplification and phase conjugation self-oscillation in a Kerr medium

I. C. Khoo, Y. Zhao

In a highly-nonlinear thin Ker medium, the intersection of a strong pump beam and a much weaker probe beam produces a sizeable diffracted beam whose presence changes both the transmitted probe beam gain and the phase conjugation self-oscillation thresholds. An analytical calculation of these effects involving degenerate multiwave mixing processes is presented.>
