Summary:The present invention relates to a tuneable add/drop demultiplexer. The add/drop multiplexer includes at least one NxN MMI-waveguide (10), where N>=3, at least N-number of Michelson waveguides (31, 32, 33 and 34), at least one Bragg grating (62, 64 and 66) per Michelson waveguide (31, 32, 33 and 34) and at least one phase control element (51, 53, 55 and 57) in at least N-1 number of Michelson waveguides (31, 32, 33 and 34). The Michelson waveguides (31, 32, 33 and 34) include said phase control elements (51, 53, 55 and 57) and said Bragg gratings (62, 64 and 66) and are coupled to at least one MMI-waveguide (10). Each Michelson waveguide (31, 32, 33 and 34) can be provided with a broadband reflection section (70). The invention also relates to a method for tuneable add/drop multiplexing, the use of a wavelength selective switch as a tuneable add/drop multiplexer and the use of a tuneable add/drop multiplexer as a wavelength selective switch.
