Self-Organization of Materials with Walking and Talking Molecules
J.-M. Nunzi, R. Barille, S. Ahmadi Kandjani and S. Kucharski

We report on the self-organization followed by propagation of a surface relief pattern. It is induced in a polymer film by using a low-power and small-size coherent beam assisted by a high-power and large-size incoherent and unpolarised beam. We demonstrate that we can obtain large size and well organized patterns starting from a dissipative interaction. This work is extended to nonlocal communication between two laser light beams and is experimented in photochromic polymer thin films. Information exchange between the beams is mediated by the self-induction of a surface relief pattern. The process can be applied to experiment on a new kind of logic gates.
