Two-dimensional optical interconnection using two photorefractive crystals

摘要

We demonstrate an optical setup being capable of transferring a two-dimensional picture in either way from one plane to another. The transferring takes place only when the receiving port sends a requesting signal. This setup consists of a LiNbO_3 crystal for the purpose of four-wave mixing, and a BaTiO_3 crystal for the purpose of producing self pumped phase conjugate wave. The characteristic of this setup is that it does not require any change in the experimental arrangement when the transferring direction of the picture is reversed. Finally, this setup can perform not only static but also dynamic image transferring.
