Raman-Nath theory of degenerate four-wave mixing in semiconductors

David J. Richardson, Ewan M. Wright, Stephan W. Koch

A theory of degenerate four-wave mixing in the Raman-Nath approximation is developed that includes transverse effects and excitation-dependent optical material properties. A microscopic model is used for the nonlinear absorption and refractive-index changes of laser-excited semiconductors. Diffusion of the excitation density is assumed to be the dominant transverse coupling mechanism. Numerical simulations of the Raman-Nath scattering spectrum are presented for the example of room-temperature bulk GaAs using steady-state illumination. The shortcomings of the standard analysis at high excitation are demonstrated.

Bifurcation of scattering orders in degenerate four-wave mixing

Ewan M. Wright, David J. Richardson, S. W. Koch

Novel bifurcating scattering orders are predicted for the Raman-Nath regime of degenerate four-wave mixing in a medium that displays optical bistability due to increasing absorption.

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

I. C. Khoo, Francesco F. Simoni, G. Cipparrone +2 more

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.
