Abstract: The invention provides a hermetic waveguide seal, such as in an optical fiber ribbon feedthrough, or in an optical fiber ferrule or feedthrough, having an optical waveguide, a glass solder for encasing at least a portion of the optical waveguide, a first glass sleeve for encasing at least a first portion of the glass solder, a second glass sleeve for encasing at least a second portion of the glass solder, and an outer sleeve for encasing at least a portion of the first glass sleeve and the second glass sleeve. A gap filled with glass solder may be provided between the first glass sleeve and the second glass sleeve to form a compressive seal. The hermetic waveguide seal is made by an extrusion process.

Abstract: A drive towards automation, particularly in the fiber optics industry, has necessitated the use of materials and methods better suited for use by machines. The present invention takes advantage of the magnetic properties of these materials to create a strong magnetic bond between separate elements while they are being connected. Two independently controllable chucks are used to align the elements in accordance with design requirements. After proper alignment, the elements are magnetically attracted together and then permanently fixed using any one of a variety of standards methods, such as welding. In the embodiment of the invention used specifically in the fiber optics industry, the alignment process includes measuring the light transmitted or reflected by the two elements.

Abstract: Automated manufacturing in the fiber optics industry has introduced a series of new problems due to the small size of the parts being assembled and the precise optical alignments required. However, processes requiring the manual assembly of parts using glue are slowly being replaced by automated processes involving the laser welding of metallically encased optical parts. Unfortunately, almost every step in the process causes a small degree of misalignment, which may cause the device to fall below transmission standards. The present invention provides a method of assembling an optical device which includes special steps that involve re-aligning the elements in the optical device after other steps in the method have caused a misalignment. In particular, the method of the present invention includes testing the alignment of the optical elements at several stages throughout the assembly process, and applying addition asymmetric welds to the finished product to improve the transmission results.
