We propose a novel planar optical interconnection scheme for 100 Gb/s optical packet address detection, which consists of waveguide grating couplers and a diffractive microlens integrated on a glass substrate 3‐dimensionally. Length and duty cycle of the grating couplers have been determined on the bases of the ray‐optic propagation‐mode analysis in a slab waveguide and of the rigorous coupled‐wave diffraction analysis for out‐coupled radiation‐modes. The 3‐dimensionally integrated planar optics makes it possible to connect each address bit‐signals of TE 0 ‐waveguide mode to the detector with a power uniformity of 6.4 % and a total coupling efficiency of 72.3 %.
