An optical coupling device for coupling of integrated optical components which are arranged on separate component substrates that may have different thicknesses characterized by a base substrate, at least two component substrates disposed on the base substrate and arranged closely adjacent to each other, an intermediate substrate disposed between the two component substrates and in engagement therewith, and at least one waveguide disposed on a surface of the intermediate substrate and coupled to two optical components on their respective component substrates. Preferably, the intermediate substrate, which may be either a band, fiber, a portion of a cylindrical rod, or an integral portion of one of the component substrates, provides a curved surface which enables bridging the space between the two component substrates and allows compensation for different thicknesses therebetween.
An optical coupling device for coupling of integrated optical components which are arranged on separate component substrates that may have different thicknesses, said coupling device comprising a base substrate, at least two component substrates disposed on the base substrate and arranged closely adjacent to each other, each of said component substrates having an integrated optical component disposed thereon, an intermediate substrate disposed between the two component substrates and in engagement therewith, and at least one waveguide disposed on a surface of the intermediate substrate and coupled to the optical components on the respective component substrates.
