An artificially structured dielectric material having optical pro perties which depend upon the intensity of light incident on the material is described. The material (2) comprises: an array of resiliently moveable mechanical elements (6) of a dielectric material which are attached to a substrate (4). The elements (6) are configured such that when the material is illuminated with light (8) of a selected intensity and wavelength the elements (6) move towards the region of higher intensity of the light thereby altering the optical properties of the material (2).

La présente invention concerne un matériau diélectrique à structuration artificielle, qui présente des propriétés optiques dépendant de l'intensité de la lumière incidente sur le matériau. Ce matériau (2) comprend un ensemble d'éléments mécaniques (6), qui peuvent se déplacer de manière élastique, sont constitués d'un matériau diélectrique et sont fixés au substrat (4). Ces éléments (6) sont conçus de façon que lorsque le matériau est éclairé avec une lumière (8) d'intensité et de longueur d'onde choisies, les éléments (6) se déplacent vers la région de plus haute intensité lumineuse, ce qui modifie les propriétés optiques du matériau (2).
