Abstract
Channel separation of wavelength multi/demultiplexers using a grating structure in a planar multimode slab waveguide is improved by choosing the thickness of the slab waveguide to be greater than the input diameter at least in the area of the grating structure. The aperture of the radiation incident upon the grating structure is chosen to be correspondingly smaller than the input aperture.
