title: Optical matrix-vector multiplication through four-wave mixing in photorefractive media.
abstract: We propose and describe a new method of optical matrix-vector multiplication by using four-wave mixing in photorefractive media. Using a BaTiO(3) crystal, we have demonstrated such a parallel multiplication. The results are presented and discussed.
