Abstract

In this paper the author investigated a special type of core cross-section bounded by metallic boundary. In this structure three cores embedded in a common metallic boundary. Characteristic equation in derived for the guided modes under weak guidance approximation by choosing an appropriate coordinate system. This study in done by using analytical method. From the characteristic equation, dispersion curves are obtained and interpreted.
