摘要： A structure for retaining an optical fiber, capable of not only handling a long optical fiber as one piece without causing the optical fiber as a whole to get loose but also reducing an area occupied by the optical fiber and retaining the same stably without causing micro-bending thereof to occur, wherein the optical fiber (1) is arranged so as to form planarly staggered turning portions thereof without causing intersecting parts to occur, a plurality of similar planarly staggered turning portions of the optical fiber being laminated in the same position in the direction of the thickness thereof which is at right angles to a plane on which the optical fiber is arranged, the resultant optical fiber (1) being generally retained in a sheet-like state by a fixing material (2), such as a bonding agent and a film.

摘要： An optical fiber coupler for optical fiber amplifier use in the field of optical communications is provided. The optical fiber coupler comprises: a rare earth-doped fiber as an optical amplifying element; a quasi rare earth-doped fiber for entrance of input signal light; a fused-stretch fiber portion as a multiplexing element which connects a part of the rare earth-doped fiber and a parts the quasi rare earth-doped fiber, wherein the fused-stretch fiber portion formed by stretched a fused mixture of parts of the rare earth-doped fiber and the quasi rare earth-doped fiber; and a single mode fiber which is jointed at a fused joint portion to another shortened rare earth-doped fiber connected to the fused-stretch fiber portion on a side connected by the quasi rare earth-doped fiber. The quasi rare earth-doped fiber has substantially equal propagation constant to the rare earth-doped fiber without substantially containing rare earth elements. The optical fiber coupler is fabricated by the steps of jointing a single mode fiber with a rare earth-doped fiber by fusing abutted end faces of both fibers to form a combined fiber; and fusing parallel contact parts of a quasi rare earth-doped fiber and of the rare earth-doped fiber of the combined fiber and then elongating the fused parts in a desired diameter to form a fused-stretch fiber portion.
