The orientation of bistable molecules incorporated in a polymer host is addressed and studied by means of all-optical poling. Molecular reorientation between two stable molecular forms is assigned as the origin of the optically induced second-order nonlinear optical susceptibility. We found a new non-photochromic photo-induced reaction scheme by which efficient all-optical poling is achieved. (c) 2006 Elsevier B.V. All rights reserved.
