Abstract
The optical connection to a fiber-optics connected optoelectronic device mounted on a substrate is made by an optical fiber inserted in a hole through the substrate facing the component. The walls of the hole align and locate the fiber. The invention finds an application in the manufacture of a balanced optoelectronic receiver for a coherent detection fiber-optics transmission system.
