Abstract
The letter discusses the filter bandwidths achievable with directional couplers composed of two dissimilar optical fibres. One fibre always has a step-index core while the other may be either a step-index fibre or a graded-index fibre whose core has a parabolic, triangular or cusp-shaped refractive-index distribution.
