Single-mode fiber couplers commonly are used in single-mode systems and fiber sensors to distribute and recombine optical signals. A widely used method for making single-mode fiber couplers is the fused-tapered technique.1'2" The equations that describe the coupling between tapered fibers require numerical evaluation. This requirement makes it difficult to predict the coupler response for different fiber parameters and taper geometries. The simple equation derived in this paper describes the coupling of power between two fibers and easily relates coupled power to the fiber parameters and taper geometry.
