ABSTRACT:
The invention relates to a process for making a monolithic integrated structure comprising two opto-electronic components (K, D1) connected optically by an optical guide.
It comprises the step consisting in making in situ between the two opto-electronic components at least one electrically insulating barrier (40) able to allow transmission of light between them, by one of the following means: localized doping with an element of conductivity of a given type, of a region of the structure of opposite conductivity type, epitaxial deposition of a layer of semi-insulating material.
