    • A fiber optic coupler is formed as follows. Glass optical fibers, each having a core, cladding and coating are disposed within the longitudinal aperture of a capillary tube, the fibers extending beyond each end thereof. The fibers are preferably held taut to effect a tension therein. The coating is removed from that portion of the fibers in the midregion of the tube by oxidation, depolymerization or the like. The coating remains on those portions of the fibers extending into the ends of the apertures to precisely orient the fibers within the tube. The midregion of the tube is heated, collapsed about the fibers, and drawn to reduce the diameter thereof.
    • 如下形成光纤耦合器。 每个具有芯,包层和涂层的玻璃光纤布置在毛细管的纵向孔内,纤维延伸超过其每端。 纤维优选保持拉紧以在其中产生张力。 通过氧化,解聚等方法从管的中间部分的纤维部分除去涂层。 涂层保留在延伸到孔的端部中的纤维的那些部分上,以精确地定向管内的纤维。 管的中间区被加热,围绕纤维折叠,并被拉伸以减小其直径。
