Analysis of Buried Rectangular Channel Dielectric Waveguide by Effective Index Method (EIM)

One essential component structure in integrated optics is buried rectangular waveguide. This paper attempted to overview and analyzed the buried dielectric waveguide using effective index method. This method involved in replacing buried rectangular waveguide with slab waveguide. It is used to simplify a two dimensional waveguide to a one dimensional waveguide Furthermore, it is considered as a curtail technique to analysis the optical properties of this type of waveguide. For instance, field distribution, normalized model index and propagation constant have been analyzed and proposed. In addition, the effect of waveguide dimension on both propagation constant and effective index method was described. Moreover, the light propagation has been described in terms of propagation constant and and wavelength which is 1.55 µm
