ABSTRACT:
Process for depositing and crystallizing a thin layer of organic material by means of a beam of energy.
A compact block formed of organic material is disposed adjacent one of the faces of the substrate, the block is subjected through the substrate to the action of a laser beam, so as to desorb the organic material forming the block, the substrate being optically transparent to the beam, and a relative displacement is performed between the substrate and the beam in order to sweep such faces over a given path, to enable the desorbed material to be deposited on the face of the substrate opposite the block, and the material thus deposited to be crystallized in a quasi-crystalline form.
Application to the manufacture of integrated optical products, such as lenses, mirrors, networks and the manufacture of opto-electronic components.
