Abstract

The present invention relates to an apparatus and a method for wavelength selective switching of a plurality of optical wavelength channels. The apparatus comprises two MMI waveguides interconnected by at least two Mach-Zehnder waveguide structures arranged in parallel, of which each is arranged to transmit a respective portion of the intensity of said plurality of optical wavelength channels. Each Mach-Zehnder waveguide structure comprises a demultiplexing unit, a multiplexing unit and at least two waveguides arranged in parallel, wherein the demultiplexing unit is arranged for demultiplexing of said plurality of optical wavelength channels into at least two channel groups, each waveguide arranged in parallel is arranged for transmission of a respective of said channel groups to the multiplexing unit, and is further provided with a respective multichannel wavelength selective phase control unit arranged for individual phase control of at least some channels in the respective of said channel groups, which is transmitted to the multiplexing unit, and the multiplexing unit is arranged for multiplexing of said channel groups.
