摘要:
A method has been described for making an electrical structure having an air dielectric and includes forming a first subunit including a sacrificial substrate, an electrically conductive layer including a first metal on the sacrificial substrate, and a sacrificial dielectric layer on the sacrificial substrate and the electrically conductive layer. The method further includes forming a second subunit including a dielectric layer and an electrically conductive layer thereon including the first metal, and coating a second metal onto the first metal of one or more of the first and second subunits. The method also includes aligning the first and second subunits together, heating and pressing the aligned first and second subunits to form an intermetallic compound of the first and second metals bonding adjacent metal portions together, and removing the sacrificial substrate and sacrificial dielectric layer to thereby form the electrical structure having the air dielectric.

A method is for making a multilayer circuit board from circuit board layers, each including a dielectric layer and conductive traces thereon including a first metal. The method includes forming a through-via in a first circuit board layer, plating the through-via with the first metal, and coating a second metal onto the first metal of the first circuit board layer, the plated through-via, and the first metal. The method also includes aligning the first and second circuit board layers together so that the plated through-via of the first circuit board layer is adjacent a feature on the second circuit board layer, and heating and pressing the aligned first and second circuit board layers so as to laminate the dielectric layers together and form an intermetallic compound of the first and second metals bonding adjacent metal portions together.

An electro-optical device may include a substrate having opposing first and second surfaces and an opening extending therebetween. The optical device may also include an optical waveguide extending laterally along the first surface and having an end aligned with the opening, and an electro-optical component carried by the second surface and aligned with the opening. The electro-optical device may further include an elastomeric body within the opening and having a first end face adjacent the optical waveguide and having a second end face adjacent the electro-optical component. The elastomeric body and the optical waveguide may have respective gradient refraction indices within ±5% of each other.

An optical device may include a substrate and an optical waveguide carried by the substrate and having a notch therein defining a feed optical waveguide and a longitudinal optical waveguide section on opposite longitudinal sides of the notch. The optical device may also include a transverse optical waveguide section carried by the substrate and transversely aligned with the feed optical waveguide adjacent the notch. The optical device may further include an elastomeric waveguide switch body configured to be moved between a first position within the notch and operative to switch light from the feed optical waveguide to the longitudinal optical waveguide section, and a second position removed from the notch and operative to switch light from the optical waveguide to the transverse optical waveguide section.

A repeatable optical waveguide interconnection may include first and second optical waveguides having respective first and second end faces. Each of the first and second optical waveguides may include a core having a core index of refraction, and a cladding surrounding the core and having a cladding index of refraction different than the core index of refraction. The interconnection may further include a first index matching elastomeric solid layer having a proximal face coupled to the first end face, and a distal face opposite the proximal face to be repeatably optically coupled to the second end face. The first index matching elastomeric solid layer may have an index of refraction profile matching an index of refraction of the core and the cladding.

A repeatable optical waveguide interconnection may include first and second optical waveguides having respective first and second end faces. Each of the first and second optical waveguides may include a core having a core index of refraction, and a cladding surrounding the core and having a cladding index of refraction different than the core index of refraction. The repeatable optical waveguide interconnection may further include a first index matching elastomeric solid layer having a proximal face chemically bound to the first end face and a low-tack distal face opposite the proximal face to be repeatably optically coupled to the second end face. Further, the first index matching elastomeric solid layer may have an index of refraction matching at least the index of refraction of the core.
