A challenging issue to design devices for photonic applications is to achieve a complete manipulation of the molecular order. Azo-dye aromatic polymers have been shown to offer interesting prospects for material engineering using light matter interactions. Dual-frequency irradiation using appropriate combinations of circular beams polarizations are demonstrated to enable full control of the molecular polar rotation. More recent results on photoinduced surface-relief gratings have also opened the way of molecular translation control using optical fields. Understanding of the relevant parameters of molecular translation processes is a key issue for optimization of such optomechanical effect: a simple model accounting qualitatively for the essential features of photoinduced surface-relief gratings is presented. It illustrates the application of optically powered molecular motors.
