Paper Abstract

We propose a bidirectional multi-channel cross-connector for two-way optical communications with array of the photorefracttinve crystal. The communication channels are connected bidirectionally by double phase conjugation in each photorefractive crystal. The wiring pattern is possible to determine by the beam that controls whether it generates the double phase conjugation in the crystal. This all-optical switching is effective method to solve the problems of the electrical wiring techniques such as the electro-magnetic interference and the thermal generation. We analyze the connection efficiency for coupling strength of the two four-wave mixing interaction region in the double phase conjugation and investigate teh intensity of control beams for sufficiently switching. We also experiment on the bidirectional connection switch and estimate the connection efficiency and the transmission efficiency.
