Planar Optical Interconnections for 100Gb/s Packet Address Detection

摘要

We propose a novel planar optical interconnection scheme for 100Gb/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 hit-signals of TEo-waveguide mode to the detector with a power uniformity of 6.4% and a total coupling efficiency of 72.3%.
