    摘要: An optical coupler and method of making thereof. The coupling ratio of the coupler is polarization-insensitive. The optical coupled described herein is made from single-mode optical fibers (12, 14). Each optical fiber has a length of nearly exposed core (20, 22) which is fused to the exposed core of the other optical fiber while the fibers are maintained in parallel juxtaposition with one another without twisting (24). By creating a fused core coupler from single-mode optical fibers in which the cores are in parallel juxtaposition with one another, the coupling ratio of the subject invention does not change with changes in polarization of light passing through each single-mode fiber and, thus, is polarization insensitive.
