摘要： An electro-optic beam controller, material processing apparatus, or optical amplifier, and corresponding methods, can include an actively controlled, waveguide-based, optical spatial mode conversion device. The conversion device can include a coupler, which can be a photonic lantern, configured to combine light beams into a common light beam; a sensor configured to measure at least one characteristic of the common light beam; and a controller configured to modulate optical parameters of the individual, respective light beams to set one or more spatial modes of the common light beam. Actively controlled and modulated devices can be used to maintain a stable, diffraction-limited beam for use in an amplification, communications, imaging, laser radar, switching, or laser material processing system. Embodiments can also be used to maintain a fundamental or other spatial mode in an optical fiber even while scaling to kilowatt power.

摘要： A multimode fiber coupler has a structure in which a plurality of tapered pump fibers are coupled laterally to a multi-clad fiber, , such as a double clad fiber (DCF). Such coupler is produced by first forming a plurality of tapered pump fibers and positioning them around the multi-clad fiber, thus forming a fiber bundle. Then, the fiber bundle is twisted and fused so that the input pump fibers converge towards a waist and then diverge from it. The diverging portions of the pump fibers may be removed from the structure. Also, at the waist, the structure may be cleaved and the portion with the converging pump fibers is then spliced with a multi-clad fiber which is similar or identical to the one in the middle of the bundle.

The input is at the signal wavelength, which is the wavelength where amplification or lasing occurs. Each of the fibers in the bundle is cleaved individually or as a group and fiber ends are aligned in the same plane. The fiber amplifier or fiber laser may include a double clad fiber and the other fibers of the bundle couple light for cladding pumping. The device may also include a mode filter for controlling the output mode.

摘要： In one aspect, the invention concerns fused fiber optic couplers (10) of the type formed from fibers (12) of transparent substance each having a circular cross section of preselected diameter. The fibers include a central fiber (14) and at least one ring of closely packed surrounding fibers with at least some of the fibers being optical fibers that have a core (16, 18) and a surrounding cladding (20, 22). The coupler (10) is formed by the processes of providing the fibers, assembling them in a close-packed relationship, and heating and drawing the assembly of fibers in the close-packed region. We have discovered that the steps involved in forming such a coupler (10), introduce slight size variations that can seriously affect the performance of the coupler, and that these slight variations can be accommodated by slight, controlled, under-sizing of one or more of the surrounding fibers (12) or over-sizing of the central fiber (14).

摘要： Optic fiber coupler fabrication stations allow one-step packaging and reduce fabrication time. The optic fiber coupler fabrication stations produce a single piece construction of the coupler package with improved uniformity. Two linear translation stages (10 and 12) are driven in opposing directions using left and right hand threaded rods connected to a common drive shaft driven by a small electric motor (16). Fibers (15) to be coupled are clamped into the station to provide the necessary tension during the tapering process. The fibers (15) are tied together using cotton thread, and an oxy-propane torch (30) is used to fuse the fibers together while the two translation stages (10 and 12) pull the fibers (15) to form a biconical tapered region in the fibers.

摘要： An optical 1xN star coupler has a single mode input fibre (I) and N single mode output fibres (01) forming an output fibre assembly. The output fibres (0) are tapered within a former (2) which holds each output fibre (0) so it is positioned substantially identically relative to the remaining output fibres. The input fibre (I) is also tapered such that the fundamental mode field of the input fibre (I) and output fibre assembly are substantially equal. The identical relative positions of the output fibres (0) provides a wavelength independent 1 x N star coupler.
