Abstract
Directional couplers are the most widely used passive devices in modern optical fiber transmission systems. However, the dispersion effects in a directional coupler have not been thoroughly investigated. Recent work indicates that the common understanding, i.e., the dispersion in a coupler is governed by the group-velocity dispersion, is not correct. This paper argues that with the coupled-mode theory, pulse distortion in a coupler is caused mainly by the frequency dependence of the coupling coefficient.
