发明名称 Wide-band optical fiber coupler and its manufacturing method.
摘要 Two optical fibers (11, 12) are stretched to form prestretched portions (13, 14) of different diameters, and then the optical fibers are fused together at their prestretched portions to form a coupling region (15), which is stretched to obtain a wide-band optical fiber coupler of a desired splitting ratio.
