  • Abstract
    We present an accurate coupled-mode analysis to evaluate the coupling characteristics of identical single-mode graded-index fiber directional couplers. We also give an empirical relation for calculating the coupling length of a fiber coupler formed by fibers having profile parameter q , normalized frequency V , and normalized separation d/a ; d is the distance between the fiber centers and a , the radius of the fiber core.
