OPTICAL STRUCTURE PROVIDED WITH AT LEAST TWO ELEMENTS ASSEMBLED BY MOLECULAR ADHESION AND METHOD FOR ASSEMBLING SAID TWO ELEMENTS

摘要

The invention relates to a method for assembling two elements of an optical structure by joining faces, wherein at least one element comprises at least one optical guide whose core is slightly sunken with respect to the joining face thereof, consisting in selecting an element whose joining face is ground for flatness and roughness prior to forming the optical guide core used in the form of an element comprising at least one optical guide, after formation of the optical guide core, in preparing the surface of the joining faces of two elements of the optical structure in such a way that it is possible to carry out the assembly thereof by molecular adhesion, in bringing into contact the joining faces and in carrying out annealing at a temperature of the order of 150 °C for reinforcing the adhesion of the assembled faces.
