Abstract: An all-optical-fiber device (optionally produced with the use of laser machining) containing constituent optical fiber components in which the corresponding ends are segmented (and—in one specific case—quartered) and optionally tapered (while portions of the original cores and claddings are maintained) and operationally joined back to form an aggregate end of the device with the round aperture and the corresponding round facet.

Constituent optical fiber component(s) and overall detection system and method for manufacture and/or use of same.

Abstract: A process of formation of an optical fiber termination includes intentionally introducing gas vent gaps within the optical fiber termination, as a result of which fabrication process related mechanical stresses in the termination are greatly or at least substantially reduced.

Abstract: Articles of manufacture, including terminations of or attachments to optical fibers are configured to substantially prevent axial emission and redirect radially most if not all light emanating from optical fibers. In that, a termination may include a fiber cap of a unitary construction of a tube and an optical element disposed to face a sealed end of the tube and dividing a hollow of the tube and having a conical surface, or an optical element dividing the hollow and complemented by a cone. An example of termination includes an optical fiber element having an up-tapered end with a maximum taper-diameter exceeding the core-diameter and ending at a conical element with an apex angle from about 70° to about 100°. Articles of manufacture additionally including mounting contraptions cooperating such terminations with cannulae to form an attachment to a laser system. Methods for transmitting light through such articles of manufacture.

Abstract: A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfering surface that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.
