A multi-wavelength processor and method comprising an input (601) and plural outputs (602, 603, 604), plural inputs and one output or at least one input (711,712) and at least two outputs (703,704), a pixellated spatial light modulator (622,722), a dispersion device (620,720), and a focussing device (621,721), the processor and method being arranged to spatially distribute input light by wavelength to different transverse positions forming group of pixels on the pixellated spatial light modulator, addressing a sub-hologram on said groups of pixels of the spatial light modulator, whereby light of a respective wavelength incident on a said hologram is processed by the respective holograms and directed to a selected output. |
