Recently, the scheme of bi-directional optical communication with a mutual-pumped phase conjugate mirror (MPPCM) has attracted attention. Bi-directional communication enables the integration of devices because input port and output port can be shared. We propose a new design for all-optical bi-directional interconnection with double MPPCMs. This interconnection is composed of two photorefractive crystals and a polarized beam splitter which is located between two crystals. The bi-directional connection is formed via two MPPCMs produced by illumination of the signal beams and the control beam. In this interconnection, the wiring pattern can be reconfigured flexibly by changing the spatial distribution of the control beam without any adjustment of the signal beams. The signal beams and the control beam are orthogonal polarized, so the signal beams can be transmitted without energy loss in dividing with control beam. In addition, the signal beams transmitting through the two crystals enhance the MPPCMs efficiently under the appropriate condition. After the buildup of MPPCMs, the connection is maintained without consecutive illumination of the control beam. Therefore the self-holding is achieved and it enables the interconnection with lower power consumption. In this paper, we analyze the optimum intensity ratio of the control beam for the signal beam in order to obtain high connection efficiency. Moreover, we confirm the self-holding of connection experimentally using BaTiO₃ crystals and Ar⁺ laser without consecutive illumination of the control beam and show the connection can be maintained for several hundred times as long as the time constant of the crystal.

We propose an all-optical interconnection with double mutual-pumped phase conjugate mirrors (MPPCM). The bi-directional interconnection is possible by using single MPPCM, however it is difficult to reconfigure the wiring pattern because the incident angle or location of the signal beams must be readjusted to buildup the new communication lines. In our interconnection, the bi-directional connection between channels is formed by the two MPPCMs produced by the illumination of the signal beams and the control beam. Therefore, the wiring pattern can be reconfigured flexibly by changing the spatial distribution of the control beam without any adjustment of the signal beams. In addition, the self-holding of connection can be achieved because the signal beams diffracted by the MPPCM illuminate the other MPPCM and the holograms in MPPCMs are maintained even if the control beam is cut off. It enables the suppression of control beam power consumption. We investigate the connection efficiency of this interconnection in order to estimate the optimum beam splitter reflectivity and intensity ratio of signal beams for obtaining higher connection efficiency and lower coupling strength threshold for the establishment of connection. We also confirm the self-holding of connection experimentally using the BaTiO₃ crystals and the Ar⁺ laser and show that the connection is maintained for several hundred times as long as the time constant of the crystal.
