Abstract

A branching filter having a multi-layered-dielectric-slab-waveguide structure is proposed, and its theoretical characteristics are analyzed by using both a coupled wave theory and an electromagnetic wave theory. Coupling coefficients required for perfect periodicity of the field configurations in the propagation direction, positional selectivity, wavelength selectivity, relations between the coupling coefficients and the structural and material constants, and an numerical example obtained by an exact application of an electromagnetic wave theory are described. The branching of this kind will be a useful device when the dimensions and the material constants can be well controled.
