A package including optical components has one or more structures with optical input or optical output. An optical interconnection optically connects to the optical input or optical output of the structure(s). A component is provided in which the optical interconnection and the optical input or optical output of the structure(s) are embedded. The component is made of a first material and the optical interconnection of a second material. The first and second materials are chemically identical. The first material has a first primary and/or secondary structure and the second material has a second primary and/or secondary structure. The first primary and/or secondary structure is different from the second primary and/or secondary structure. The refractive indices of the component and of the optical interconnection differ from each other by at least 0.0004 at 850 nm, 1,310 nm, and 1,550 nm, respectively. The optical interconnection is mechanically fixed by the component.
