  • Process for manufacturing vertical optical coupling structures
    Patent number: 10073228
    Abstract: The present invention relates to a method for manufacturing vertical optical coupling structures (1) between first optical or optoelectronic components (2) and second optical or optoelectronic components (3). Said vertical optical coupling structures are made by: (1) depositing a main layer (A) onto a substrate (25) 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 (12) consisting of a material having a refractive index greater than the refractive index of air.
    Type: Grant
