The directional coupler structure comprises two waveguides, wherein the waveguides arranged exhibit different effective diffractive index. The waveguides in one section are arranged in the proximity of each other, such that an optical field in the first waveguide can overlap a second waveguide and vice versa and that in said section at least two gratings are arranged for co-directional coupling. Said gratings are arranged isolated from each other. The invention further comprises a method for switching of wavelength channels through the use of said multi-wavelength selective switch.
