摘要： The present invention provides improved collimating lens assemblies (32), improved methods of reducing the optical power density in collimating lens assemblies, and to improved fiber optic rotary joints (31) incorporating such improved collimating lens assemblies. The improved collimating lens assembly broadly includes: a singlemode fiber (38) terminating in a distal end; a step-index multimode fiber (44) having a proximal end abutting to the singlemode fiber distal end, and having a distal end; a graded-index multimode fiber (45) having a proximal end abutting the step-index multimode fiber distal end, and having a distal end; and a collimating lens (34) longitudinally spaced from the graded-index multimode fiber distal end by an intermediate air gap (43), and operatively arranged to collimate light rays emanating from the graded-index multimode fiber distal end. The improved collimating lens assembly is characterized by the fact that there is no epoxy, silicone gel or index-matching material between the graded-index multimode fiber distal end and the collimating lens. Rather, these various elements are fusion-spliced together. The improved collimating lens assembly is capable of handling energy levels that are typically used in various wavelength division multiplexing techniques.

摘要： A slip ring and brush assembly comprises a gold plated slip ring surface and a bundle of conductive fibers in the 2 to 3 mil size range. During use, gold transfers from the ring to the fibers, and the resulting gold-on-gold contact interface of ring and brush is extremely noise free and long wearing.

摘要： The present invention provides several improvements in a slip ring (36) that is adapted to provide electrical contact between a rotor (42) and stator (40). In one aspect, a brush tube (39) is crimped around the upper marginal end portions of a plurality of individual fibers (38) inserted therein. In another aspect, a collimator tube (41) extends downwardly beyond the end of the brush tube to limit lateral movement of the fibers in the bundle when the rotor rotates. In yet another arrangement, a spring (55, 56) is arranged to bear against a current-carrying conductor to adjustably vary the force by which the lower ends of the fibers are urged to move toward the rotor.

摘要： An m-input/n-output (e.g. 1×1, 1×2, 2×2) optical fiber switch includes a switch substrate formed with v-grooves in which singlemode fibers are disposed with their ends operatively arranged in relation to a deflecting mirror to transmit or receive optical signals. To prevent misalignment between the optical paths defined by these singlemode fibers, a lens is fused to directly to each of the singlemode fiber ends to eliminate the need for separate collimating lens and create a stable and dimensionally invariable interface between the fiber and the lens, resulting in a more compact optical switch arrangement.
