| In this thesis work the filtering and coupling performance of an add/drop filter is analyzed. The basic add/drop filter which has been considered in this thesis consists of two identical and parallel single mode slab waveguides, coupled by a resonant cavity of a planar shape. A number of planar cavity shapes were considered. This includes, for example, the rectangular, the bow-tie, the hexagonal and the parallelogram shaped cavities. The Method of Lines (MOL) using the Layer by Layer Algorithm has been applied to model these add/drop filters.;Keywords. Method of Lines (MOL), Add/Drop Filter, The Layer by Layer Algorithm. |
