| Outline of Final Research Achievements |
In this project, we proposed to utilize wavefront propagation in two-dimensional opto-thermal bistable device for natural computing. We call it “solid-state natural computing”, since the device is in solid state and utilize light as the energy source. We have demonstrated the basic function of the device by numerical simulation using the finite element method and by experiment using devices with liquid crystal. In addition, we demonstrated maze exploration, and found that this device presents the reduction mode that has been never realized by any natural computing device except for true slime mold. We also examined further functionalization with external feedback, and demonstrated that the refractory feedback can provide pulse operation.
