Abstract

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.
