Coupling properties of a directional coupler based on two adjacent AHPMW waveguides. (a) Schematic of the wavelength-selective component, (b) the corresponding 3D |E| evolution, (c) dependence of the mode effective index and the coupling length on the separation, and (d) propagation lengths of the even and odd modes as functions of S.
