Abstract

The present invention is directed to a package including optical components, comprising: (i) at least one structure, the structure having at least one optical input or output, (ii) at least one optical interconnection, optically connected to the at least one optical input or output, and (iii) a component in which the at least one optical interconnection and the at least one optical input or output is embedded, wherein (a) the component (iii) embedding the at least one optical interconnection and the at least one optical input or output and the at least one optical interconnection (ii) are made from a chemically identical material, wherein the material of the at least one optical interconnection has a different primary and/or secondary structure, compared to the material of the component embedding the at least one optical interconnection and the at least one optical input or output, (b) the component (iii) embedding the at least one optical interconnection and the at least one optical input or output and the at least one optical interconnection (ii) have a difference in their refractive indices of at least 0.0004 to 0.0015 at 850, 1310, and 1550 nm, respectively, and (c) the at leas…
