Four-wave mixing with matter waves
Nature, 1999The advent of the laser as an intense source of coherent light gave rise to nonlinear optics, which now plays an important role in many areas of science and technology. One of the first applications of nonlinear optics was the multi-wave mixing1,2 of several optical fields in a nonlinear medium (one in which the refractive index depends on the ...

Four-Wave Frequency Mixing in Gases
1987Four wave frequency mixing in gases is now understood in a quantitative manner and has been used for the design of coherent infrared as well as vacuum uv sources. A brief review of the fundamental processes is given. The vacuum uv sources have already extended laser spectroscopy into the vacuum ultraviolet spectral region below 200 nm. Several examples

Multiple four-wave mixing in optical fibres
2014 The European Conference on Optical Communication (ECOC), 2014We propose a general formulation to derive the set of equations of a multiple four-wave mixing process involving any number N of waves, equally spaced in frequency. We compare the model with experimental results for N=6 and find excellent agreement.

Forward four-wave mixing with defocusing nonlinearity
Optics Letters, 2007We experimentally demonstrate degenerate, forward four-wave mixing effects in a self-defocusing photorefractive medium, in both one and two transverse dimensions. We observe the nonlinear evolution of new modes as a function of propagation distance, in both the near-field and far-field (Fourier space) regions.

Four-wave mixing and six-wave mixing in a four-level confined atomic system
Chinese Physics B, 2009We have investigated coexisting four-wave mixing and six-wave mixing (SWM) in ultra-thin, micrometre and long vapour cells. There exists competition between Dicke-narrowing features and polarization interference in the micrometre cell. The oscillation behaviour of SWM signal intensities and linewidths results from destructive interference.

Four-Wave Mixing in Metamaterials
Russian Physics Journal, 2018Interaction of four counterpropagating waves in a cubic medium being “left” for the signal wave is considered in the constant-intensity approximation. Analytical expression for the signal wave intensity is derived for the general case of four-wave interaction in a metamaterial.

Instabilities In Four-Wave Mixing
SPIE Proceedings, 1986Recent research on instabilites in the four-wave mixing process is summarized. The four-wave mixing process can cause a laser beam to become unstable to the growth of new frequency components as the beam propagates through a nonlinear medium. Similar instabilities can occur in more complicated optical systems such as lasers and bistable optical devices.

One characteristic of nonlinear processes in quantum optics is the occurrence of products of interaction energies with complex conjugates of these energies, e.g., in the third-order product VV*V. This is built into the concept of the rotating-wave approximation, whether taken classically or quantum mechanically.

1999
The present chapter is devoted to presenting the theory of four-wave mixing in semiconductor optical amplifiers (SOAs). At first, a model describing the dynamics in terms of rate equations is developed. The rate equations are derived from density matrix equations, and after coupling with the propagation equation for the field envelope and its phase, a ...
