Abstract: A device for generating an electrical signal that is a function of the optical power in an optical fiber. The device is comprised of a support substrate, a fused, bi-conically-tapered splitter-coupler, and a glass bead securing an optical fiber extending from the splitter-coupler to the substrate. An opening in the glass bead forms a gap in the optical fiber. A light-sensitive device is disposed in the opening to receive light traveling through the optical fiber from the splitter-coupler.

Abstract: A package for a fiber optic device or fiber optic component having at least one optical fiber extending therefrom. The package is comprised of a support substrate for supporting the optical device or optic component, the support substrate having at least one optical fiber extending therefrom. A housing surrounds the substrate and has an opening at one end. At least one optical fiber extends through the opening. A layer of metal seals the opening of each end of the tube and the glass fiber cladding where the optical fiber extends through the layer of metal. The layer of metal is applied using a thin film deposition process, such as ion-beam assisted deposition, electron-beam deposition, or ion-beam deposition.

Abstract: A package for a fiber optic device or component comprised of an elongated support substrate for supporting an optical device or component having at least one optical fiber extending therefrom. The optical fiber has an inner glass core and a glass cladding surrounded by an outer buffer. An elongated glass tube is dimensioned to receive the support substrate. The glass tube has open ends. The at least one optical fiber extends through one of the open ends with the outer buffer removed from the optical fiber in the vicinity of the open end. A glass seal surrounds the inner glass fiber closing the open ends.
