Abstract: A protective assembly method using a transparent layer within the fiber interconnect system aids in optical coupling by preventing an air gap from forming between the fiber cores within a connector. A thin transparent film (or with adhesive) is placed over the fiber end-faces at the connector interface, the film having characteristics which allows it to conform to the fiber end and minimize coupling loss between fibers. The film is sized to fit connectors faces and can be temporary, being replaced with each installation. A coating can also applied to the connector surface, providing a similar effect, as well as structurally enhancing the connector surfaces.

Abstract: A fiber optic transceiver that is compatible with packaging into standard semiconductor packages and for SMT packaging, using materials and fabrication procedures that withstand solder assembly processes. The SMT package can have electrical contacts on the exterior of the package for creating electrical conduits to a substrate, such as a PCB, interposer, or circuit card within a larger assembly. The fiber optic transceiver can be of a non-SMT package configuration, being formed with electrical connection technology that allows direct connection to a substrate with electrical wiring, such as a PCB, interposer, or circuit card within a larger assembly. The fiber optic transceiver may have solderballs, metal posts or other electrical conduit technology that allows direct electrical connection to the substrate.

Abstract: Systems and methods are described for creating a very cost effective optical/electrical interface connecting system with high tolerance to misalignment. Low cost sealed optical devices can be fabricated with easily detachable top cable assemblies. This approach can be used for hermetically sealed optical devices without the need for hermetic fiber feed-through. The system also has features that enable fiber optic components to operate and survive in harsh environments, particularly in large temperature extremes.

Abstract: A system for creating an optical time domain reflectometer (OTDR) in a small package is described. This system allows the implementation of multiple channels of OTDR in package of similar size to existing fiber optic transceivers.

Abstract: A device structure and system for connecting optical waveguides to optical transmit and receive components is described. The structure is made of two parts. The lower part contains active optoelectronic components, such as lasers and photodetectors, and optical lenses. The lower part can be assembled by steps of aligning and bonding planar components. The upper part contains optical waveguides and lenses for coupling light into and out of the waveguides. The top part is mechanically connected to the lower part to form a mechanically sound connection. The lens system provides some tolerance to mis-alignment between the top and bottom parts. The system has features that enable fiber optic components to operate and survive in harsh environments, particularly large temperature extremes.

Abstract: A component system and method is described that is made of components for transmitting, routing and receiving “in-air” optical signals for placement on printed wiring boards (PWBs). The transmitters are components including a light source attached to a transparent substrate and aligned to a coupling lens. The transparent substrate can contain circuitry for controlling the light source, or the circuitry could be attached to the transparent substrate. The receivers include a light detector attached to a transparent substrate with circuitry for converting optical signals to electrical circuitry (integrated onto the transparent substrate or separately attached). The routing components include a lens for coupling light into an optical waveguide, an optical waveguide and, optionally, a second lens for coupling light from the optical waveguide.
