Title: Production of d-shaped fiber
Inventor: NISHIURA YOZO
IPC: G02B6/287
Filed: 1984-11-14
Abstract: PURPOSE:To improve the accuracy of a D-shaped fiber and to mass-produce the fiber by a simple method, by forming a semicircular perform of the fiber by grinding one side of an original perform of the fiber having an almost circular cross section and forming the D-shaped fiber by wire-drawing the semicircular preform. CONSTITUTION:The side part 56 of a preform 44 having a circular cross section shown by the hatch is removed by grinding and another preform 58 having an almost semicircular cross section is produced. The preform 58 is wire-drawn by a wire drawing device and an optical fiber is produced. In the course of this wire-drawing, the drawing speed is lowered so that the optical fiber thus produced can have a cross section which is very similar to that of the preform 58. Since the diameter of the preform 58 is reduced to about 1/200 by this wire- drawing, the distance from its core 42 to the outer surface 60 of the cladding layer at the linear section becomes shorter and the distance hardly fluctuates and, as a result, a high-performance optical fiber coupler can be obtained easily. Therefore, the accuracy of this D-shaped fiber can be improved and the fiber can be mass-produced by such a simple method.
