Abstract
By treating a fused tapered single-mode fiber coupler as a perturbation of the same coupler with the fiber cores ignored, simple analytical expressions are derived for the coupling coefficients of the coupler. These new expressions highlight the effects of the fiber cores on the characteristics of the coupler.
