Abstract
The present invention relates to a method for manufacturing vertical optical coupling structures () between first optical or optoelectronic components () and second optical or optoelectronic components (). Said vertical optical coupling structures are made by: () depositing a main layer (A) onto a substrate () including second optical or optoelectronic components; and (ii) lithography and/or physico-chemical etching of the main layer. Each vertical optical coupling structure is made such as to be located facing and making contact with a second optical component located in the substrate. The unitary main layer comprises generally frusto-conical coupling portions () consisting of a material having a refractive index greater than the refractive index of air. The coupling portions each have: a first transverse end surface () for making contact with the sending or receiving surface () of a first optical or optoelectronic component; and a second transverse end surface () that is in contact with the sending or receiving surface () of the second optical or optoelectronic component.
