Abstract
The disclosure relates to encapsulated optical fiber end-coupled devices. An optical assembly may include a fiber holder and a cap with an optical component mounted to its underside. The optical component may be aligned with a fiber passing between a substrate and a second section of the fiber holder to allow optical signals to be coupled between the optical component and the fiber. Techniques for assembling the fiber holder and the cap may facilitate the formation of hermetic seals to provide a protective environment for the optical component.
Claims36
An apparatus comprising:
- an optical fiber holder including:
- a substrate with a recess formed in a first surface;
- a second section attached to the first surface of the substrate and including an opening defining an inner surface;
- a cap attached to the second section of the optical fiber holder such that the second section of the fiber holder is disposed between the cap and the substrate, the cap including an underside, wherein the recess in the first surface of the substrate, the inner surface of the opening in the second section and the underside of the cap define an interior region, and wherein the cap includes a conductive through-hole to provide an electrical connection from outside the interior region to the underside of the cap;
- an optical fiber mounted to the substrate and passing between the substrate and the second section to the interior region;
- and
- an optical component mounted to the underside of the cap and in electrical contact with the conductive through-hole, the optical component being positioned with respect to the optical fiber to allow an optical signal to be coupled between the optical fiber and the optical component.

A method comprising:
- positioning an optical fiber on a substrate that includes a recess in a first surface, an end of the optical fiber extending to an area defined by the recess;
- fixing a second section to the substrate so that a portion of the fiber passes between the substrate and the second section;
- providing a material through a hole in the second section to fix the fiber in place, the hole being located adjacent the portion of the fiber passing between the substrate and the second section;
- positioning a cap on the second section so that the second section is disposed between the substrate and the cap, the cap including an optical component mounted to its underside, wherein, when the cap is positioned on the second section, the optical component is encapsulated within an interior region defined by the recess in the substrate, an inner surface of an opening in the second section, and the underside of the cap;
- and
- fixing the cap to the second section with the optical component aligned with the optical fiber to allow an optical signal to be coupled between the fiber and the optical component.
