Abstract

A method of making of an optical device provided with a nano-structured or micro-structured component assembled on one end of an optical fibre includes providing a carrier based on a material photosensitive and transformable into a vitreous material, and making on a first end of the carrier, by two-photon photopolymerization, a micro-structured or nano-structured component, based on a material photosensitive and transformable into a vitreous material. The method also includes performing one or more heat treatment(s) so as to transform the material of the carrier and the material of the micro- or nano-structured component into a vitreous material and, then, assembling and securing a region of a second end of the carrier opposite to the first end with an area of an end of the optical fibre, by localised fusion of the region and the area, respectively of the carrier and the optical fibre.
