Abstract: A device for converting transverse spatial profile of intensity of a light beam, using a microstructured optical fiber. Transverse dimensions of the fiber vary longitudinally and both its ends have opto-geometrical parameters such that at the wavelength of the beam the fiber has a fundamental mode having two different profile shapes at its two ends. Thus by introducing the beam with one of the profiles through one of the two ends, the beam emerges through the other end with the other profile, whose shape is different from that of the profile of the introduced beam.

Abstract: An optical communication cable includes a jacket, optical transmission elements, and armor. The jacket is mostly formed from a first material and includes an elongate member formed from a second material embedded in the first material. The jacket defines a channel in which the optical transmission elements are located. The armor includes a wrapped sheet having a lateral edge and is positioned around the optical transmission elements within the channel. The elongate member has an inner surface aligned with and located exterior to the lateral edge of the armor; and, when viewed in cross-section, the elongate member fully overlays and extends tangentially beyond the lateral edge. Accordingly, the elongate member provides an obstacle in the jacket that limits zippering through the jacket originating from the lateral edge. Further, the elongate member may double as a tear feature for quickly accessing contents of the cable interior to the jacket.
