1. An optical device for all-optically multiplexing or demultiplexing light of substantially different predetermined wavelengths, the optical device comprising:

  • at least one first dielectric waveguide formed on a substrate;

    at least one second dielectric waveguide formed on said substrate, said at least one first dielectric waveguide and said at least one second dielectric waveguide intersecting at an intersection; and

    a diffraction grating structure formed at said intersection, wherein said diffraction grating structure is adapted for diffracting light of a first predetermined wavelength from said at least one first dielectric waveguide in a coupling direction, and for diffracting light of a second predetermined wavelength from said at least one second dielectric waveguide in substantially the same coupling direction which is substantially different from the normal direction on the average plane defined by the grating structure, the first predetermined wavelength and the second predetermined wavelength being substantially different.
