Summary:
Bistable system with a spatial expanse can support a traveling wavefront, an interface between two stable states. We investigate a two-dimensional optical bistable device (2DOBD) for natural computing including maze exploration. In our device, wavefront propagation is flexibly controllable by light intensity and other parameters. In this paper, we describe complex dynamics in wavefront propagation due to an external feedback. Refractory feedback can provide not only periodic but also unstably fluctuating pulse trains that may be chaotic.
