Microwave-developed three-dimensional real-time holography.
A new technique capable of enhancing optical nonlinearity is proposed. In the suggested scheme, weak optical fields create a three-dimensional real-time hologram written as a carrier distribution, and then an applied microwave field develops the hologram by heating the carriers and increasing the nonlinear refractive index locally. As an example, we have calculated the diffraction efficiency for the case of four-wave mixing. A value as high as 1% can be achieved in a 5-mm sample of CdS microcrystallites in glass.
