four-wave mixing

Show Summary Details

Quick Reference

In nonlinear optics, the production of a photon in a medium as a result of the interaction of three photons. In four-wave mixing, the photon produced has a wavelength (frequency) that is different from the wavelength (frequencies) of any of the three original photons. The effect is important in optical fibres; it can lead to loss of signal when a number of wavelengths are transmitted along the same fibre.
